ADS122S14
Eight-channel 24-bit, 64kSPS delta-sigma ADC with PGA, VREF, two IDACs and SPI
ADS122S14
- Low power consumption (as low a 57µA)
- Wide supply voltage range:
- Analog: 1.74V to 3.6V
- Digital: 1.65V to 3.6V
- Programmable gain: 0.5 to 256
- Programmable data rate (up to 64kSPS) and speed mode to trade power consumption and noise performance
- Simultaneous 50Hz and 60Hz rejection at 20 or 25SPS with single-cycle settling digital filter
- Analog multiplexer with 8 independently selectable inputs
- Dual-matched programmable current sources
- Internal programmable voltage reference:1.25V or 2.5V with 25ppm/°C (max) drift
- Internal 1% (max) accurate oscillator
- Internal temperature sensor
- Four general-purpose I/Os (push-pull or open-drain output)
- SPI-compatible interface with optional CRC and daisy-chain capability
The ADS1x2S14 are precision, low-power, 16- and 24-bit, analog-to-digital converters (ADCs) that offer many integrated features to reduce system cost and component count in the most common sensor measurement applications. The devices feature eight analog inputs through a flexible input multiplexer (MUX), a low-noise, programmable gain amplifier (PGA), a programmable low-drift voltage reference, two programmable excitation current sources, an oscillator, and a temperature sensor.
Four speed modes, with programmable output data rates from 20SPS up to 64kSPS, allow to optimize power consumption and noise performance for each application. At output data rates of 20SPS and 25SPS, the integrated digital filter offers simultaneous 50Hz and 60Hz line-cycle rejection with single-cycle settling.
