This circuit produces a 0- to 10-kHz output in response to a 0- to ± 10-V input. The A4 output indicates the sign (+ or -) of the input. To calibrate, apply either a - 10- or + 10-V input and set the 10-kΩ trim for exactly a 10-kHz output. The low offsets of A1 and A2 permit operation down to a few Hz with no zero trim required.
