3.Description
The ADS1220 is a precision 24-bit analogue-to-digital converter (ADC) that provides a number of integrated features to reduce system cost and part counts for measuring small sensor signals.
The device implements two differential or four single-ended inputs via a flexible input multiplexer (MUX), whisper, programmable gain amplifier (PGA), two programmable excitation current sources, a voltage reference, an oscillator, a low-side switch, and a precision temperature sensor.
The device can convert at a data rate of 2000 samples per second (SPS) with single-cycle settling. At 20 SP, digital filters provide simultaneous 50 Hz and 60 Hz rejection for noisy industrial applications.
The internal PGA provides high gain to 128 V/V.
The PGA makes the ADS1220 ideally suited for applications that measure small sensor signals such as resistance temperature detectors (RTDs), thermocouples, thermistors, and resistance bridge sensors.
