ADS7949SRTET

Analog To Digital Converters (ADC) Overview

The ADS7949SRTET is a Texas Instruments 8-bit successive approximation register (SAR) analog-to-digital converter featuring two input channels. It operates at a standard sample rate of 2 MSPS using a 16-clock data frame, with optimized performance up to 3 MSPS via a short data frame. The device supports pseudo-differential or single-ended inputs and utilizes an external reference. Power supply ranges include 2.7 V to 5.25 V for analog circuits and 1.65 V to 5.25 V for digital logic. It functions within a temperature range of -40°C to +125°C and is housed in a 16-WQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ET' indicates the tape and reel packaging configuration when ordering. Confirm that the external reference voltage requirements align with the system design, as the device does not include an internal reference. Ensure compatibility with the 1.65 V to 5.25 V digital interface levels required for SPI communication.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring moderate resolution with high throughput. Compare against the ADS7947 (12-bit) and ADS7948 (10-bit) if higher precision is needed, noting that increased resolution may reduce maximum sampling speed. Verify that the 8-bit dynamic performance meets the signal-to-noise ratio requirements of the target application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS794x family of ultralow-power ADCs from Texas Instruments. The family includes the ADS7946 (14-bit), ADS7947 (12-bit), ADS7948 (10-bit), and ADS7949 (8-bit). All members share similar pinouts and interfaces but vary in resolution and maximum sampling rates based on the data frame configuration.
