ADS931E/1K

Analog To Digital Converters (ADC) Overview

The ADS931E/1K is an 8-bit, high-speed pipelined analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a sampling rate of 33 MHz and operates from standard +5V or +3V power supplies. The device includes a high-bandwidth track-and-hold circuit and an 8-bit quantizer with digital error correction logic to ensure excellent differential linearity. It utilizes a 28-pin SSOP package and supports single-ended input ranges such as 1V to 2V at +3V supply or 2V to 4V at +5V supply. The full-scale input range is configurable via an external reference voltage.

Analog To Digital Converters (ADC) Feature Summary

• High-speed pipelined architecture with 33 MHz sampling capability
• Integrated digital error correction for improved linearity

• Low power consumption suitable for battery-operated equipment

Analog To Digital Converters (ADC) Applications

• Battery-powered equipment
• Camcorders
• Portable test equipment
• Digital cameras
• Communications systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '1K' against the official datasheet to confirm it denotes the tape-and-reel packaging variant rather than a functional difference. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Confirm availability status as older generation components may have limited stock or end-of-life implications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 33 MHz sampling speed are sufficient for the application. It is appropriate for designs requiring low power consumption and a single-ended input interface. Consider the need for an external reference voltage source, as the device does not include an internal reference. Evaluate the 28-pin SSOP package constraints against PCB layout space.

Analog To Digital Converters (ADC) Part Context

The ADS931E belongs to Texas Instruments' family of high-speed analog-to-digital converters designed for imaging and telecommunications applications. It is part of the ADS931 series, which shares similar architectural characteristics but may vary in pinout or packaging options. This specific model represents the commercial grade version available in a 28-lead SSOP package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS930 is a similar 8-bit, 30 MHz sampling ADC from the same manufacturer. The ADS830 offers higher speed at 60 MHz. Verify pin compatibility and performance specifications before substituting.
