ADS7888SDBVR

Analog To Digital Converters (ADC) Overview

The ADS7888SDBVR is a single-channel, 8-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates within an analog and digital supply voltage range of 2.35 V to 5.25 V. The device supports a maximum sampling rate of 1.25 MSPS with a serial peripheral interface (SPI) compatible data output. Key performance metrics include a signal-to-noise ratio of 49.5 dB, differential nonlinearity of 0.3 LSB, and integral nonlinearity of +/- 0.3 LSB. Power consumption is specified at 3.8 mW typical and 7.5 mW maximum. It functions in temperatures from -40°C to +125°C and is housed in a SOT-23-6 surface-mount package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the device meets RoHS compliance standards for your region. Ensure the design accounts for moisture sensitivity level 2 requirements during storage and handling. Validate that the SOT-23-6 thermal characteristics align with your system's dissipation limits under maximum operating conditions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 1.25 MSPS speed are sufficient for the application. Consider the single-ended input limitation compared to differential alternatives. Evaluate the SOT-23-6 package size against available PCB real estate. Compare power consumption figures with other SAR ADCs if battery life is a critical constraint.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER™ series of data converters from Texas Instruments. It shares architectural similarities with the ADS7887 but offers higher resolution. The device is often paired with Texas Instruments operational amplifiers or voltage regulators for complete signal conditioning chains. Development kits like the ADS7888EVM provide evaluation support for circuit designers.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7888SDBVT is a tape-and-reel variant of the same functional device. Check datasheet revisions for any marking or electrical parameter updates before substituting. Verify pin compatibility if replacing with other 8-bit SAR ADCs from different manufacturers.
