ADS7820U

Analog To Digital Converters (ADC) Overview

The ADS7820U is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Burr-Brown. It features a serial interface for data output and operates with a single power supply. The device integrates a track-and-hold amplifier to ensure accurate sampling of input signals. Key electrical specifications include a maximum conversion time of 6 microseconds and an integral nonlinearity error of ±1 LSB, ensuring precise data acquisition without missing codes. The component is housed in an 8-pin SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with ±1 LSB integral and differential nonlinearity
• Serial interface compatible with standard microprocessors
• Integrated track-and-hold amplifier for signal conditioning
• Single-supply operation capability

Analog To Digital Converters (ADC) Applications

• Battery-powered systems requiring low power consumption
• Remote data acquisition modules
• Industrial process control monitoring
• Portable test and measurement instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Burr-Brown or Texas Instruments, noting that Burr-Brown was acquired by TI. Confirm the 'U' suffix indicates the SOIC-8 package variant. Check RoHS compliance status as older revisions may not meet current environmental standards. Ensure the operating temperature range matches the specific grade required for the application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate speed and high resolution is needed for single-channel applications. Compare against the ADS7816 or ADS7817 if multi-channel inputs are required, as those devices offer eight channels. Verify that the serial interface timing requirements align with the host processor's clock capabilities. Consider power consumption constraints relative to the sampling rate.
