ADS8517IBPWR

Analog To Digital Converters (ADC) Overview

The ADS8517IBPWR 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 range of 4.5 V to 5.5 V and a digital supply range of 1.65 V to 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 rated at 60 mW, and it functions within a temperature range of -40°C to +85°C in a 28-pin TSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix 'PW' corresponds to the TSSOP-28 tube packaging variant when sourcing. Confirm that the specific revision matches the required interface timing specifications. Ensure the analog and digital supply voltages align with the 4.5–5.5 V and 1.65–5.25 V ranges respectively. Check for RoHS compliance status as indicated in official documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-resolution 16-bit conversion at moderate speeds. Consider the dual interface capability if system flexibility between parallel and serial connections is needed. Evaluate power constraints against the 60 mW dissipation rating. Verify thermal management requirements for the TSSOP-28 package in enclosed environments.
