The the relationship of the gain value and control the level: The main parameters of the integrated chip's PGA102: The figure shows the data gain high speed cascade amplifying circuit. This circuit is composed of the umerical control instrument amplifier INA110 and the gain programmable integrated op-amp PGA102. When the 3 pin of the INAll0 connects with the pins 13, the voltage amplifier multiples is Av = 10. The control of the gain circuit is compeleted by the first level 2 PGA102 integrated op-amp.
