CS289 - 20mA Air-Core Tachometer Drive Circuit
The CS289 is specifically designed for use with air-core meter movements.
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 so
