ADS820U/1K

Analog To Digital Converters (ADC) Overview

The ADS820U/1K is a low-power, monolithic 10-bit Analog-to-Digital Converter (ADC) from Texas Instruments. It utilizes a pipeline architecture with digital error correction to guarantee no missing codes and excellent differential linearity. The device operates from a single +5V supply and supports both differential and single-ended input configurations. Key electrical specifications include a sampling rate of 20 MSPS, a Signal-to-Noise Ratio (SNR) of 60 dB at 25°C, and a power consumption of 195 mW. It features an internal reference and is available in SO-28 and SSOP-28 packages.

Analog To Digital Converters (ADC) Feature Summary

• Pipeline A/D converter with digital error correction for guaranteed no missing codes
• Low differential linearity error of ±0.2 LSB typical
• Internal reference with external bypass options for REFT and REFB pins
• Wideband track-and-hold circuit with 65 MHz full-power bandwidth

Analog To Digital Converters (ADC) Applications

• Set-top boxes
• Cable modems
• Video digitizing
• CCD imaging systems
• IF and baseband digitization

Analog To Digital Converters (ADC) Procurement Notes

Verify the '/1K' suffix indicates tape and reel packaging containing 1000 devices per reel. Confirm the 'U' designation corresponds to the SO-28 package variant. Check current production status as datasheet dates may indicate obsolescence or lifecycle changes. Ensure handling precautions are observed due to ESD sensitivity.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed 10-bit conversion with low power dissipation. The internal reference simplifies design but can be overridden by external references if higher drive capability or adjusted full-scale range is needed. Ensure the clock source provides a 50% duty cycle with fast rise/fall times to maintain SNR performance.

Analog To Digital Converters (ADC) Part Context

The ADS820U/1K belongs to the ADS820 family of high-speed ADCs. The 'U' suffix denotes the SO-28 plastic package, while 'E' denotes the SSOP-28 package. The '/1K' suffix specifies the shipping quantity and media type (Tape and Reel). This part is distinct from other ADS series converters which may offer different resolutions or interface types.
