ADS7816UC

Analog To Digital Converters (ADC) Overview

The ADS7816UC is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Burr-Brown. It features a high-impedance fully differential analog input and operates with a single 5V supply. The device supports sampling rates up to 200 kSPS while maintaining micro-power consumption, typically 1.9 mW at full speed. It utilizes a synchronous serial interface compatible with standard microprocessors. Key electrical specifications include a maximum conversion time of 6 µs, an integral nonlinearity error of ±2 LSB, and a differential nonlinearity of ±1 LSB. The operational temperature range extends from -40°C to +85°C.

Analog To Digital Converters (ADC) Part Context

The ADS7816UC belongs to the ADS781x family of high-speed, micro-power ADCs from Burr-Brown. This series was engineered to balance speed and power efficiency for 12-bit applications. The 'UC' suffix denotes the specific package variant and commercial temperature rating (-40°C to +85°C). Texas Instruments acquired Burr-Brown, and these components are now often referenced under TI part numbers with equivalent specifications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADS7816U (industrial grade) or ADS7816EB. For system upgrades requiring similar performance, the ADS7834 offers comparable 12-bit SAR architecture. Verify that the substitute component matches the required package type and voltage specifications before integration.
