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 2.0 V to 6.0 V. This is accomplished by

shown in Figure 12 uses an external op amp as a buffer and

operates over an input voltage range of 0 V to 4.0 V.
