AD7173-8BCPZ

AD7173-8 fast settling, highly accurate, low power, 8/16-channel, multiplexed ADC for low bandwidth input signals with integrated input buffers. Eight flexible setups with configurability for output data rate, digital filter mode, offset/gain error correction, reference selection, buffer enables and more. This per channel configurability extends to the output data rate used for each channel when using sinc5 + sinc1 filter. Integrated diagnostic features, including CRC, register checksum, temperature sensor, crosspoint multiplexer, burnout currents and GPIOs/GPOs. Typical applications include process control: PLC/DCS modules (voltage, current, temperature and pressure measurement, flow meters), medical and scientific multichannel instrumentation, seismic instrumentation, chemical analysis instrumentation: chromatography.
