Overview
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 major and ±1.
00° for the minors.
The interface from the microcontroller is by a SPI compatible serial connection using up to a 2.
0 MHz shift clock rate.
The digital code is shifted into the appropriate DAC and multiplexe...
