High performance combined with low cost and low power
consumption make our Analog-to-Digital Converters (A/D
Converters) ideal for portable instrumentation, embedded control
and data acquisition applications. Microchip’s portfolio includes
Delta-Sigma A/D Converters with up to 22-bit resolution and
sampling speeds up to 60 samples per second. Successive
Approximation Register (SAR) A/D Converters have 10-, 12- and
13-bit resolutions with sampling rates up to 200 ksps. Also
included are Dual Slope A/D Converters with high resolution of
up to 17 bits with fully differential inputs, plus BCD and Binary A/
D Converters which feature over-range and under-range detection.
The MCP3905/6 devices are Energy Measurement ICs that
output a frequency proportional to the average active (real) power
at the inputs. The MCP3905/6 devices incorporate two 16-bit
Delta-Sigma ADCs with a progammable gain up to 16 or 32,
which enable small shunt meter designs for measuring a wide
range of IB and IMAX currents.
Select from low-cost serial D/A Converters, Voltage-to-Frequency
Converters (V/F), Frequency-to-Voltage Converters (F/V) and low
dropout precision Voltage References that feature low power and
high precision. Rounding out Microchip’s Mixed-Signal Family are
the Single- and Dual-Channel Digital Potentiometers.
