TEXAS INSTRUMENTS  ADS1120IPWR  模数转换器, 16 bit, 2 kSPS, 单, 2.3 V, 5.5 V, TSSOP

The is a precision, 16-bit Analogue-to-digital Converter ADC IC, offers many integrated features to reduce system cost and component count in applications measuring small sensor signals. The device features two differential or four single-ended inputs through a flexible input multiplexer MUX, a low-noise, 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 perform conversions at data rates up to 2000 samples-per-second SPS with single-cycle settling. At 20 SPS, the digital filter offers simultaneous 50 and 60Hz rejection for noisy industrial applications. The internal PGA offers gains up to 128V/V. The device supports measurements of pseudo- or fully-differential signals when using the PGA.
