CS4172 Datasheet (Cherry Semiconductor Corporation)

CS4172, Single Air-Core Gauge Driver

The CS4172 is a monolithic BiCMOS integrated circuit used to translate a digital 10-bit word from a microprocessor/microcontroller to complementary DC outputs.

The DC outputs drive an air-core meter commonly used in vehicle instrument panels.

The 10 bits of data are used to linearly control the quad
