CS289 Datasheet PDF - Cherry semiconductor

Description
The CS289 is specifically designed for use with air-core meter move ments. The IC has charge pump circuitry for frequency-to-voltage conversion, a shunt regulator for stable operation, a function generator, and sine and cosine amplifiers. The buffered sine and cosine outputs will typically sink or source 20mA.

FEATUREs
■ Single Supply Operation
■ On-Chip Regulation
■ 20mA Output Drive Capability
