ADS774HIDWR

Analog To Digital Converters (ADC) Overview

The ADS774HIDWR is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 125 kS/s and supports single-ended input signals. The device features a parallel interface for microprocessor compatibility and includes both internal and external reference options. It functions within an analog supply voltage range of 4.5 V to 5.5 V and a digital supply voltage of 4.5 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 72 dB, integral nonlinearity of +/- 0.5 LSB, and power dissipation of 120 mW. The component is housed in a 28-pin SOIC package and operates across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IDWR' against official Texas Instruments documentation to confirm pinout and electrical characteristics, as variations exist within the ADS774 family. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to procurement. Ensure the source document explicitly lists this exact part number to avoid substitution errors with similar variants like ADS774HIBDWR or ADS774KU.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 125 kS/s throughput are required for single-ended signals. The parallel interface necessitates sufficient GPIO availability on the host processor. Consider the 120 mW power dissipation for thermal management in enclosed designs. Verify that the 4.5 V to 5.5 V supply range aligns with the system's power architecture before finalizing the selection.
