CS4172 Description
The CS4172 is a monolithic BiCMOS integrated circuit used to translate a digital 10-bit word from a microprocessor/microcontroller to plementary DC outputs. The DC outputs drive an air-core meter monly used in vehicle instrument panels. The 10 bits of data are used to linearly control the quadrature coils of the meter directly with a 0.35¡ resolution and ±1.0¡ accuracy over the full 360¡ range of the gauge.
