ADS1220 ADC for Small Signal Sensors

TI's low-power, low-noise, 24-bit analog-to-digital converter

Image of Texas Instruments' ADS1220 ADC for Small Signal Sensors Texas Instruments' ADS1220 is a precision, 24-bit, analog-to-digital converter (ADC) offered in a leadless QFN-16 or a TSSOP-16 package. The device features two differential or four single-ended inputs through a very flexible input multiplexer (mux), a low-noise, programmable gain amplifier (PGA), two programmable excitation current sources, an internal reference, an oscillator, a low-side bridge switch, and a precision temperature sensor. The many integrated features and the simple control of the ADS1220 through an SPI-compatible interface ease precision measurements of the most common sensor signals.
