onsemi Specialized ICs CS8190EDWFR20G

The CS8190EDWFR20G is a precision air-core tachometer and speedometer driver IC designed for use with air-core meter movements. It accepts a speed sensor input and generates sine and cosine output signals to drive the meter differentially. This IC features enhancements over standard tachometer drivers, including differential output drivers that eliminate the need for a zener reference and provide increased torque. It can withstand voltage transients up to 60 V, reducing the need for additional protection circuitry. The device operates within a supply voltage range of 8.5 V to 16 V and has a low supply current of 50 mA at 16 V. It offers high input impedance, low pointer flutter, and overvoltage protection. The CS8190EDWFR20G is available in a Pb-free, RoHS-compliant SO-20W package and includes internally fused leads. Its operating temperature range is from -40 ¬8C to +105 ¬8C, making it suitable for various applications.
