... The CS8190 is specifically designed for use with air–core meter movements. The IC provides all the functions necessary for an analog tachometer or speedometer. The CS8190 takes a speed sensor input and generates sine and cosine related output signals to differentially drive an air–core meter. Many enhancements have been added over industry standard tachometer drivers such as the CS289 or LM1819 ...

... Note: Temperature, voltage and nonlinearity not included. CIRCUIT DESCRIPTION and APPLICATION NOTES The CS8190 is specifically designed for use with air–core meter movements. It includes an input comparator for sensing an input signal from an ignition pulse or speed sensor, a charge pump for frequency to voltage conversion, ...

... F/V output but will also increase the response time. An increase in response time causes a very slow meter movement and may be unacceptable for many applications. The CS8190 has an undervoltage detect circuit that disables the input comparator when V falls below 8.0 V(typical). CC With no input signal the F/V output voltage decreases and the needle moves towards zero ...

... In some cases a designer may wish to use the CS8190 only as a driver for an air–core meter having performed the F/V conversion elsewhere in the circuit. Figure 11 shows how to drive the CS8190 with a DC voltage ranging from 2 6.0 V. This is accomplished by forcing a voltage on the F/V lead ...
