SA5775AN Description
The SA5775A is a monolithic driver for controlling air-core (or differential) meters typically used in automotive instrument cluster applications. The circuit interfaces with a microprocessor through a serial bus and directly drives the air-core meter. The SA5775A has 10-bit resolution (0.35 degree) and is guaranteed to be monotonic.
