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
