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 multiplexer. These two blocks provide a tangential conversion function to change the digital data into the appropriate DC coil voltage. The major gauge driver can position a pointer anywhere within a 360 circle while the minor gauge drivers are limited to an arc of 112.2.
