ADS931E

Analog To Digital Converters (ADC) Overview

The ADS931E is an 8-bit, 33MHz sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a high-speed pipelined architecture with a track/hold circuit and digital error correction logic to ensure excellent differential linearity. The device operates from standard +3V or +5V power supplies, consuming 69mW at +3V. It features a single-ended input range of 1V to 2V when powered by +3V, or standard ranges like 2V to 4V with +5V. The full-scale input range is adjustable via an external reference. The ADS931E is housed in a 28-lead SSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E' against the manufacturer's datasheet to confirm temperature grade and availability status. Confirm that the SSOP-28 package matches the design requirements. Check for any obsolescence notices or lifecycle changes directly from Texas Instruments documentation before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS931E when an 8-bit resolution and 33MHz sampling speed are sufficient for the application. Ensure the system can accommodate the required single-ended input voltage range (1V-2V for +3V operation). Verify that an external reference voltage source is available to set the full-scale range. Consider the SSOP-28 package size constraints during PCB layout.

Analog To Digital Converters (ADC) Part Context

The ADS931E belongs to the ADS931 family of high-speed pipelined ADCs from Texas Instruments. It shares architectural similarities with other devices in the series but is distinguished by its specific 8-bit resolution and 33MHz sampling capability. This component is designed for applications requiring moderate speed and resolution with low power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS930 is a similar 8-bit, 30MHz sampling ADC from the same family. Verify pin compatibility and electrical parameter differences, such as sampling rate and power consumption, before substituting. Consult the official datasheet for detailed comparison of performance metrics.
