ADS8517IBPW

Analog To Digital Converters (ADC) Overview

The ADS8517IBPW is a low-power, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input architecture and supports both parallel and SPI digital interfaces. The device operates with an analog supply voltage ranging from 4.5 V to 5.5 V and a digital supply voltage between 1.65 V and 5.25 V. It achieves a sampling rate of 200 kSPS with a typical signal-to-noise ratio of 89 dB and a signal-to-noise and distortion ratio of 88.5 dB. Differential nonlinearity is specified at -1/1.5 LSB, while integral nonlinearity is +/- 1.5 LSB. Power consumption is limited to 60 mW, and it functions within a temperature range of -40°C to +85°C in a 28-pin TSSOP package.
