12-bit SAR ADC, 1 MSPS, SOT-23-6
The ADS7886SBDBVR is a 12-bit successive-approximation-register (SAR) analog-to-digital converter from Texas Instruments' microPOWER™ series, sampling at 1 MSPS through a single-ended input. The SPI data interface keeps the pin count low; the converter communicates over just three or four lines, which suits space-constrained designs where the host MCU has a spare SPI port.
The analog and digital supply pins share the same 2.35 V to 5.25 V range, which simplifies rail planning: one LDO or regulator feeds both sides, and the reference is the supply itself.
It is ROHS3 compliant, so it passes the material-restriction check for EU and most global markets without an exemption review.
