ADS7822PC

Analog To Digital Converters (ADC) Overview

The ADS7822PC is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Burr-Brown, now part of Texas Instruments. It operates on a single power supply ranging from 2.7V to 5.25V. The device supports sampling rates up to 200kHz while maintaining low power consumption, drawing only 1.6mW at full speed. It features an asynchronous serial interface compatible with standard microprocessors and DSPs. The component is housed in an 8-pin plastic small outline (SO-8) package, designed for space-constrained applications requiring high-speed data acquisition.

• Industrial process control loops
• Portable medical devices

Analog To Digital Converters (ADC) Part Context

The ADS7822 series was originally developed by Burr-Brown Corporation before its acquisition by Texas Instruments. The 'PC' suffix denotes the SOIC-8 package variant. This component belongs to a family of micro-power ADCs that includes variants like the ADS7816 and ADS7817, differentiated primarily by speed and voltage specifications. It serves as a general-purpose solution for mid-range precision applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADS7822EB (MSOP-8 package) or ADS7822E (DIP-8 package). For higher resolution needs, the ADS8320 (16-bit) may be considered if speed requirements allow. Verify package compatibility when substituting between SOIC, DIP, and MSOP variants.
