ADS7888SDCKR

Analog To Digital Converters (ADC) Overview

The ADS7888SDCKR 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 SPI interface. 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. It is housed in a SC-70-6 surface-mount package and functions across a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure ESD handling protocols are followed due to the small form factor and sensitivity of the SAR architecture components during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring 8-bit resolution at high speeds up to 1.25 MSPS. Compare against the ADS7887 if higher 10-bit resolution is needed, noting the trade-off in SNR. Verify that the single-ended input type matches the signal source requirements. Check thermal specifications against the expected operating environment limits.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADS788x family of microPOWER ADCs. The family includes variants like the ADS7886 (12-bit), ADS7887 (10-bit), and ADS7888 (8-bit). All share similar low-power characteristics and serial interfaces but differ in resolution and noise performance. The SDCKR variant specifically denotes the SC-70-6 package with reel packaging.
