Sample-and-hold amplifier circuit with SMP04 op amp and 10 gain

Published:2013/2/20 0:25:00 Author:Ecco | Keyword: Sample-and-hold , amplifier , op amp , 10 gain

Sample-and-hold amplifier circuit with SMP04 op amp and 10 gain
The circuit will place SMP04 in the feedback loop of op amp OP490, when S Non / H = 0, OP490 feedback loop is turned off, SMP04 internal switch is closed, the op amp gain of the circuit is decided by the op-amp and the feedback resistor, the gain in figure is set to 10, the output terminal outputs the amplified sampled voltage. When S non / H = 1, SMP04 internal switch is turned off, the op amp OP490 feedback loop can not form. (View)
