ADS7822EB/2K5G4

Analog To Digital Converters (ADC) Overview

The ADS7822EB/2K5G4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a sampling rate of 75 kSPS and operates with an analog supply voltage range of 2.7 V to 5.25 V. The device utilizes a 3-wire serial interface compatible with standard SPI protocols. It is housed in an 8-pin VSSOP package and supports pseudo-differential input configurations. Key performance metrics include a differential nonlinearity (DNL) and integral nonlinearity (INL) of ±0.75 LSB, with a signal-to-noise and distortion ratio (SINAD) of 71 dB. The component is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the /2K5 designation corresponds to the 2500-unit reel packaging format. Ensure the VSSOP-8 package variant matches the intended PCB footprint requirements. Cross-reference the manufacturer part number against current datasheets to confirm active status and any potential obsolescence notices before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between moderate speed and ultra-low power is required. The 75 kSPS rate suits applications where bandwidth demands are lower than the 200 kSPS variants. The external reference requirement allows for optimized noise performance using precision references. Consider the VSSOP package constraints regarding thermal dissipation and soldering profiles during design integration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7822 family of micro-power ADCs from Texas Instruments. It shares architectural similarities with the ADS7822E and ADS7822U but differs in package type and sampling rate specifications. The EB suffix typically denotes the VSSOP package variant, distinguishing it from the SOIC-based U series or other tape-and-reel configurations within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include the ADS7822EC/2K5G4, which offers identical pinout and functionality in the same VSSOP-8 package. Designers may also consider the ADS7822E/250 for similar performance in alternative packaging. Verify that any replacement maintains the 75 kSPS sampling rate and 2.7 V minimum operating voltage to ensure circuit compatibility.
