ADS7822PG4

Analog To Digital Converters (ADC) Overview

The ADS7822PG4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.7 V to 5.25 V and features a single-channel pseudo-differential or single-ended input. The device supports a sampling rate of up to 200 kS/s and utilizes a 3-wire serial interface for data communication. It is housed in a 28-pin DIP package and functions within a temperature range of -40°C to +85°C. Key performance metrics include a signal-to-noise and distortion ratio (SINAD) of 71 dB, with differential and integral nonlinearity errors limited to ±1 LSB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'PG4' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering information matches the exact package type required for your PCB layout. Cross-reference the revision history to confirm any changes in electrical characteristics or recommended operating conditions compared to previous iterations.

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. Compare against the ADS7822UBG4 if a surface-mount SOIC-8 package is preferred over the through-hole DIP format. Evaluate the ADS7824 series if multiple input channels are necessary instead of a single channel. Confirm that the external reference requirement aligns with system design constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7822 family of high-speed, micropower sampling ADCs from Texas Instruments. The family includes variants with different packaging options such as the UBG4 (SOIC-8) and automotive-grade versions like the ADS7822-Q1. These devices share core architectural similarities but differ in physical footprint and qualification standards.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7822UBG4 serves as a direct functional equivalent with identical electrical specifications but utilizes an SOIC-8 surface-mount package instead of the DIP-28 form factor. Designers must adjust PCB footprints accordingly when substituting between these package types.
