It is a numerical control constant current source designed for the charge of battery. D / A converter outputs a voltage to the bottom of the op amp inverting input, the circuit current I = Uad / sampling resistor, the two PORT are used to access the battery + and - poles. The magnification of the amplifier circuit is 1/4. It is used for measuring battery voltage. The 2 adjusted tubes are 3dd13 and 3dd15.
