ADS804U

Analog To Digital Converters (ADC) Overview

The ADS804U is a discontinued 12-bit, 10MHz sampling pipelined analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a high-bandwidth track-and-hold circuit and operates on a single +5V supply with a power dissipation of 180mW. The device provides an internal reference and supports flexible input ranges, including 2Vp-p and 5Vp-p options. It utilizes a parallel data interface and is housed in a 28-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 10Msps sampling rate
• High spurious-free dynamic range (SFDR) of 80dB at Nyquist
• Internal voltage reference with selectable input ranges
• Over-range indicator flag for input monitoring

Analog To Digital Converters (ADC) Applications

• Intermediate frequency (IF) digitization
• Baseband digitization
• CCD imaging systems
• Test instrumentation

Analog To Digital Converters (ADC) Procurement Notes

The ADS804U is classified as obsolete by the manufacturer. Verify availability through secondary distributors or consider replacement components from the active ADS804 family, such as the ADS804E, which offers identical electrical specifications in a different package format.

Analog To Digital Converters (ADC) Selection Notes

Select this component only if legacy compatibility with the 28-pin SOIC form factor is required. For new designs, the pin-compatible ADS804E (SSOP-28) or ADS805 (20MHz) are recommended alternatives that maintain functional equivalence while ensuring current production status.

Analog To Digital Converters (ADC) Part Context

The ADS804U belongs to the ADS804 family of high-speed ADCs. It shares architectural similarities with the ADS803 (5MHz) and ADS805 (20MHz), allowing for design flexibility across varying speed requirements within the same product line.
