ADS7822UB/2K5G4

Analog To Digital Converters (ADC) Overview

The ADS7822UB/2K5G4 is a discontinued 12-bit analog-to-digital converter (ADC) from Texas Instruments, part of the microPOWER series. It features a single SAR architecture with a sampling rate of 200 kS/s and accepts pseudo-differential inputs via an SPI interface. The device operates on dual power supplies: analog and digital voltages range from 2.7V to 3.6V or 5V. Housed in an 8-SOIC package, it supports surface mount mounting and functions within an operating temperature range of -40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

This component is officially discontinued and no longer carried by major distributors such as DigiKey. Verification of current availability through alternative channels or secondary markets is required before procurement planning. Designers should confirm end-of-life status with the manufacturer to ensure long-term supply chain stability for production runs.

Analog To Digital Converters (ADC) Selection Notes

Engineers selecting this part must account for its discontinued status when designing new products. Alternative components within the same family, such as the ADS7822EC or ADS7822E, offer similar specifications but may differ in package type or pinout compatibility. Reviewing the official datasheet is essential to verify electrical characteristics and interface timing requirements against specific application needs.

Analog To Digital Converters (ADC) Part Context

The ADS7822UB/2K5G4 belongs to the ADS7822 family of high-speed, low-power ADCs. The 'UB' suffix indicates the SOIC-8 package variant, while '/2K5G4' denotes the tape and reel packaging quantity and RoHS compliance. This specific part number represents a legacy version of the broader microPOWER sampling ADC line produced by Texas Instruments.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include ADS7822EC/2K5G4 and ADS7822E/2K5G4. These variants share the same core functionality but utilize different packages (VSSOP-8). Verify pin compatibility and thermal performance before substitution.
