AS1747, AS1748, AS1749, AS1750
Low-Voltage, Dual SPDT, Audio Clickless Switches with
Negative Rail Capability

Datasheet
1 General Description
The SPDT (single-pole/double-throw) switches AS1747,
AS1748, AS1749 and AS1750 allow signa ls below
ground to pass through without distortion. These analog
switches are ideal for switching audio signals, due to
their supply voltage from +1.8V to +5.5V and their low
0.4Ω on-resistance.
An included comparator offers the AS1748 and AS1750
with headphone detection or mute/send key function.
To reduce click-and-pop so unds when switching
between pre-charged points the AS1749 and AS1750
have an internal shunt switch. This shunt switch auto-
matically discharges any capacitance at the NO and NC
connection points.
This SPDT switch is available in space-saving 10-pin
TDFN 3x3 packages and operate over the -40ºC to
+85ºC extended temperature range.

8 Detailed Description
The AS1747– AS1750 are operating from a +1.8V to +5.5V supply and feature a negative signal capability that allows
signals below ground to pass through without distortion. A break-before-make switching and a low on-resistance are
also included in this analog dual SPDT switches. The device is fully specified for a 3.0V application .
A headphone or mute detection is inclu ded in the AS1748 and AS1750. This function is realized with a comparator
which has an internally generated t hresh-hold of about 1/3 of VCC. To reduce click-and-pop sounds when switching
between precharged points the AS1749 and AS1750 have an internal shunt switch. T his shunt switch automatically
discharges any capacitance at the NO and NC connection points.
9 Application Information
Digital Control Inputs
The logic inputs of the AS1747– AS1750 accept up to +5.5V independent of the supply voltage. Due to this a mixing of
the logic levels in a system is possible. For example, with a +3.3V supply, IN_ can be driven low to GND and high to
+5.5V. For a +1.8V supply voltage, the logic levels are 0.5V (low) and 1.4V (high); for a +5V supply voltage, the logic
levels are 0.8V (low) and 2.0V (high).
Analog Signal Levels
The change of the on-resistance of the AS1747– AS1750 is very little for analog input signals over the whole supply
voltage range. The switches are bi-directional, so the NO_, NC_, and COM_ pins can be either inputs or outputs.
The AS1747– AS1750 pass signals as low as VCC - 5.5V, including signals below gr ound with minimal distortion.
Comparator (AS17481/AS1750)
To implement a mute and headphone function, a comparator is included in the AS1748 and AS1750. The negative ter-
minal of this comparator is connected to the outside (via pin CMP-) while the positive terminal is internally set to VCC/3.
The output of the comparator (CMPO) is logic high when the negative terminal (CMP-) is below the threshold. CMPO is
logic low when CMP- is higher than V CC/3.
Headphone audio signals are typical biased to VCC/2 so a comparator threshold of VCC/3 is sufficient for the head-
phone detection.
Shunt Switch (AS17491/AS1750)
Due to the switching between audio sources, audible click-and-pop sounds occur . To reduce this sounds a 100Ω shunt
switch is implemented in the AS1749 and AS1750. This shunt switch automatically discharges any capacitance at the
NC_ or NO_ terminals when they ar e unconnected to COM_.
Audible clicks and pops are caused when a step DC voltage is switched into the speaker. By automatically discharging
the side that is not connected, any residual DC voltage is removed, thereby reducing the clicks and pops.
Power-Supply Sequencing and Overvoltage Protection
Caution: Stresses beyond the listed absolute maximum ratings in Table 3 on page 4 may cause permanent damage
to the device. Exposure to ab solute maximum rating conditions for extended periods may affect device
reliability.
Proper power-supply sequencing is recommended for all CMOS devices. Alwa ys apply VCC before applying analog
signals, especially if the analog signal is not current-limited.
