... Precision Air-Core Tach/Speedo Driver with Return to Zero Functional Description The IL8190N is specifically designed for use with air–core meter movements. The IC provides all the functions necessary for an analog tachometer or speedometer. The IL8190N takes a speed sensor input and generates sine and cosine related output signals to differentially drive an air– ...

... Circuit Description and Application Notes The IL8190N 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, a bandgap voltage regulator for stable operation, and a function generator with sine and cosine amplifiers to differentially drive the meter coils ...

... Increasing the value of C4 will reduce the ripple on the V/F 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 IL8190N has an undervoltage detect circuit that disables the input comparator when V falls below 8.0 V (typical). With no input CC ...

... IL8190N only as a driver for an air–core meter µF having performed the V/F conversion elsewhere in the circuit. Figure 9 shows how to drive the IL8190N with a DC voltage ranging from 2 6.0 V. This is accomplished by forcing a voltage on the V lead. The alternative scheme shown in Figure 10 uses an external op amp as a buffer and operates over an input voltage range 4.0 V. 100 kΩ ...
