As shownis the division circuit composed by integrated block 4302, the inputs are V1 and V2, its output Vo is: Vo=10V1/V2. The input signal range: 0.03V≤V1≤10V, 0.03V≤V2≤10V. The circuit's typical error is ±25mV at 25℃, the max error is ±50mV, and output voltage accuracy affected by temperature, its temperature coefficient is ±1mV/C, output disorders voltage is 士10mV at 25℃, temperature coefficient is ±lmV/C. V1, V2's bandwidth in small signal is 500 kHzin small signal (-3dB), full range output is 60kHz. The adjustment method ofR1, R2 and R3 is: when V1=V2=+10V, adjust R1 to make the output Vo = +10V; When Vl=V2=+0.1V, adjust R2 to make output Vo=+10V; When V1=+0.01V, V2=+0.1V, adjust R3 to make Vo=+1V. So can adjust again and againfor a few times.
