a low-power device integrated operational amplifier INA102. The integrated chip INA102 features are: small quiescent current (up to 750 A); internal gain through different connection pins varies, which has selectable gain: l, 10,100 and 1000, the figure pin 4, 5, 6 and 7 is connected to the pin can be connected to the largest gain of 1000; high gain accuracy and drift (up to 5 10-6 / ); common-mode rejection ratio (minimum 90dB); a small offset voltage (max l00 V); small non-linear distortion (maximum 0.01%); small offset voltage drift (max 2 V / ); high input resistance (1010 ). The circuit voltage amplification factor of 1000, the output voltage peak value of up to 1V.
