描述 Description

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. Data can be shifted through the part, allowing several SA5775As to be cascaded with only one chip-select line. On-chip current shutdown logic protects the circuit from external faults.FEATURES
? 10-Bit resolution (0.35 degrees)
? Exceptional accuracy (0.25 degrees, typical)
? High-torque capability
? Active differential drivers eliminate back-EMF issues
? No RFI/EMI generation issues
? Simple serial interface
? Simple cascading capability for multiple meters
? Internal fault protection
? Only one external component required (bypass capacitor)APPLICATION
? Instrumentation utilizing air-core meters
