CS4122 Triple Air-Core Gauge Driver

PIN # 1 2 PIN SYMBOL SCLK CS FUNCTION Serial clock for shifting in/out of data. Rising edge shifts data on SI into the shift register and the falling edge changes the data on SO. When High, allows data at SI to be shifted into the internal shift register with the rising edge of SCLK. The falling edg.

CS4122 Triple Air Core Gauge Driver with Serial Input Bus The CS4122 converts digital data from a microprocessor to complementary DC outputs and drives air core meter movements for vehicle instrument panels. It is optimized for one 360° gauge and two 112° gauges. The digital data controls the voltage applied to the quadrature coils of the meters with a 0.35° resolution for the major (360°) gauge and 0.44° resolution for the minor (112°) gauges. The accuracy is ±0.75° for the majo.
