ADS7888SDBVT

Analog To Digital Converters (ADC) Overview

The ADS7888SDBVT 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 single-ended input configuration. It features an SPI-compatible serial interface for data communication. 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, with a maximum power dissipation of 7.5 mW. The component is housed in a compact SOT-23-6 surface-mount package and functions reliably across an extended temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to ensure the correct tape-and-reel or cut-tape packaging variant matches your assembly requirements. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) prior to storage and reflow soldering processes. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current production status and availability channels.

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. Ensure the system voltage aligns with the 2.35 V to 5.25 V operating range. Consider the SOT-23-6 footprint constraints during PCB layout. Verify that the SPI interface timing meets the microcontroller or DSP requirements without additional buffering.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS788x family of micro-power ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7885 and ADS7887, differing primarily in resolution and sampling speed specifications. The SDBVT suffix indicates a specific thermal and packaging variant within the broader ADS7888 product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include the ADS7885SDBVT and ADS7887SDBVT, though differences in resolution and sampling rate must be evaluated against system requirements.
