The MAX187BEWE+: This 12-bit successive-approximation ADC samples at 75k samples per second over an SPI interface, making it a straightforward fit for medium-speed data acquisition where a single-ended input and an internal reference simplify the analog front-end.
Supply and temperature — one-rail simplicity
Both the analog and digital supplies run from a single 5 V rail, so no split-supply regulator is needed — a clean 5 V plane and a decoupling cap at each supply pin are the usual starting point.
