3 Description
The LM61 device is a precision, integrated-circuit
temperature sensor that can sense a –30°C to 100°C
temperature range while operating from a single
2.7‑V supply. The output voltage of the LM61 is
linearly proportional to temperature (10 mV/°C) and
has a DC offset of 600 mV. The offset allows reading
negative temperatures without the need for a
negative supply. The nominal output voltage of the
LM61 ranges from 300 mV to 1600 mV for a –30°C to
100°C temperature range. The LM61 is calibrated to
provide accuracies of ±2°C at room temperature and
±3°C over the full –25°C to 85°C temperature range.
The linear output of the LM61, 600-mV offset, and
factory calibration simplify external circuitry required
in a single supply environment where reading
negative temperatures is required. Because the
quiescent current is less than 125 µA, self-heating is
limited to a very low 0.2°C in still air. Shutdown
capability for the LM61 is intrinsic because its
inherent low power consumption allows it to be
powered directly from the output of many logic gates.

(5) Accuracy is defined as the error between the output voltage and 10 mV/°C multiplied by the device's case temperature plus 600 mV, at
specified conditions of voltage, current, and temperature (expressed in °C).
(6) Nonlinearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight line, over the device's
rated temperature range.
(7) Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output due to heating
effects can be computed by multiplying the internal dissipation by the thermal resistance.
(8) For best long-term stability, any precision circuit gives best results if the unit is aged at a warm temperature, or temperature cycled for at
least 46 hours before long-term life test begins. This is especially true when a small (Surface-Mount) part is wave-soldered; allow time
for stress relaxation to occur. The majority of the drift occurs in the first 1000 hours at elevated temperatures. The drift after 1000 hours
does not continue at the first 1000-hour rate.

7 Detailed Description
7.1 Overview
The LM61 is a precision integrated-circuit temperature sensor that can sense a –30°C to 100°C temperature
range using a single positive supply. The output voltage of the LM61 has a positive temperature slope of
10 mV/°C. A 600-mV offset is included, enabling negative temperature sensing when biased by a single supply.
The temperature-sensing element is comprised of a delta-VBE architecture. The temperature-sensing element is
then buffered by an amplifier and provided to the VOUT pin. The amplifier has a simple class A output stage as
shown in Functional Block Diagram.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 LM61 Transfer Function
The LM61 follows a simple linear transfer function to achieve the accuracy as listed in Electrical Characteristics.
Use Equation 1 to calculate the value of VO.
VO= 10 mV/°C × T°C + 600 mV
where
• T is the temperature in °C
• VOis the LM61 output voltage (1)
7.4 Device Functional Modes
The only functional mode of the LM61 device is an analog output directly proportional to temperature.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The LM61 has a wide supply range and a 10-mV/°C output slope with a 600-mV DC. Therefore, it can be easily
applied in many temperature-sensing applications where a single supply is required for positive and negative
temperatures.

8.2.1.2 Detailed Design Procedure
The LM61 is a simple temperature sensor that provides an analog output. Therefore, design requirements related
to layout outweigh other requirements in importance. See Layout for more information.
8.2.1.2.1 Capacitive Loads
The LM61 handles capacitive loading well. Without any special precautions, the LM61 can drive any capacitive
load as shown in Figure 12. Over the specified temperature range the LM61 has a maximum output impedance
of 5 kΩ. In an extremely noisy environment it may be necessary to add some filtering to minimize noise pickup. It
is recommended that 0.1-µF capacitor be added between +VS and GND to bypass the power-supply voltage, as
shown in Figure 13. In a noisy environment it may be necessary to add a capacitor from VOUT to ground. A 1-µF
output capacitor with the 5-kΩmaximum output impedance forms a 32-Hz lowpass filter. Because the thermal
time constant of the LM61 is much slower than the 5-ms time constant formed by the RC, the overall response
time of the LM61 is not significantly affected. For much larger capacitors this additional time lag increases the
overall response time of the LM61.

9 Power Supply Recommendations
In an extremely noisy environment, it may be necessary to add filtering to minimize noise pickup. TI recommends
a 0.1-µF capacitor be added between +VSto GND to bypass the power-supply voltage, as shown in Figure 13.
10 Layout
10.1 Layout Guidelines
10.1.1 Mounting
The LM61 can be applied easily in the same way as other integrated-circuit temperature sensors. It can be glued
or cemented to a surface. The temperature that the LM61 senses is within about 0.2°C of the surface
temperature that LM61's leads are attached to.
This presumes that the ambient air temperature is almost the same as the surface temperature; if the air
temperature is much higher or lower than the surface temperature, the actual temperature measured would be at
an intermediate temperature between the surface temperature and the air temperatures.
To ensure good thermal conductivity the backside of the LM61 die is directly attached to the GND pin. The lands
and traces to the LM61 are part of the printed-circuit board, which is the object whose temperature is being
measured.
Alternatively, the LM61 can be mounted inside a sealed-end metal tube, and can then be dipped into a bath or
screwed into a threaded hole in a tank. As with any IC, the LM61 and accompanying wiring and circuits must be
kept insulated and dry, to avoid leakage and corrosion. This is especially true if the circuit may operate at cold
temperatures where condensation can occur. Printed-circuit coatings and varnishes such as Humiseal and epoxy
paints or dips are often used to ensure that moisture cannot corrode the device or connections.

10.3 Thermal Considerations
The junction-to-ambient thermal resistance is the parameter used to calculate the rise of a device junction
temperature due to its power dissipation. For the LM61, Equation 2 is used to calculate the rise in the die
temperature.
TJ= TA+ RθJA × ((+VS× IQ) + (+VS– VO) × IL)
where
• IQis the quiescent current
• ILis the load current on the output (2)
Table 2 summarizes the rise in die temperature of the LM61 without any loading with a 3.3-V supply, and the
thermal resistance for different conditions.

(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
