This mode can achieve gain control by adopting the existing programmable gain amplifier integrated circuit directly.The diagram of circuitous philosophy is shown as picture 4.ICs at thisfield are PGA103,PGA204,AD526,AD620,THS7001 and so on andthe gain control only has fixed levels.Some magnifications are 1, 2, 4, 8, 16 times,and some are 1, 2, 4, 8, 16 times.The way setting the gain control are resistance setup,pin setup,and software setup.
