ADS1220 Breakout Board (24-bit Analog to Digital Converter)

The ADS1220 is a high precision 24-bit analog to digital converter (ADC) from Texas Instruments. It has four (4) single channels which can be used as four single-ended inputs channels or as two (2) differential input channels. Also, it has a low-noise programmable gain amplifier (PGA). The ADS1220 has two programmable excitation current sources, a voltage reference, an oscillator, a low-side switch, and a precision temperature sensor Furthermore, it offers two modes of conversion. That is, it can use either continuous conversion or single-shot conversion modes.. ADS1220 can measure two PT500 and PT1000 sensors as RTD 1,2,3,4 Wire. Features • Four channel inputs (or two differential inputs) • Voltage: 3-5V • 24-bits resolution (20-bits ENOB or effective resolution) • Programmable gain amplifier and programmable data rates • 50-Hz and 60-Hz noise rejection • Low drift internal voltage reference and accurate internal oscillator • Programmable current sources • Internal temperature sensor • SPI interface ADS1220 analog to digital module Datasheet ADS1220 ADC module Tutorial
