ADS7822UC

Analog To Digital Converters (ADC) Overview

The ADS7822UC is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single 2.7V to 5.25V analog supply and features a 3-wire synchronous serial interface compatible with standard SPI modes. The device supports sampling rates up to 200kSPS while consuming only 1.6mW of power at full speed. It utilizes an external reference voltage and accepts pseudo-differential or single-ended inputs. Packaged in an 8-pin MSOP, it functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'UC' against the official datasheet to confirm the MSOP-8 package variant and industrial temperature rating. Ensure the external reference voltage requirements align with system design constraints before procurement. Confirm RoHS compliance status through authorized distributors.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate speed and low power is required for single-channel applications. Consider the external reference requirement if system complexity must be minimized. Evaluate the MSOP package size against available PCB real estate constraints compared to SOIC alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7822 family of micro-power ADCs from Texas Instruments. It shares core specifications with variants like the ADS7822U and ADS7822EC but differs primarily in packaging and thermal grade. The UC suffix specifically denotes the MSOP-8 package option designed for space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include ADS7822U (SOIC-8) and ADS7822EC (VSSOP-8). Verify that the alternative package type meets mechanical clearance requirements. Performance parameters such as sampling rate and resolution remain consistent across these variants.
