The digital controlled constant flow source

Published:2011/6/10 1:04:00 Author:Seven | Keyword: constant flow source | From:SeekIC

This is a digital controlled constant flow source of battery charging, which is designed by me. D/A converter outputs a voltage to the same polarity of the downside, the current in the circuit is I=Uad, it is fixed with sampling resistance, and two PORTs are used to connect the + and - poles. The upside transporting circuitry is connected as a amplifier circuit of 1/4 times, which is used to test the voltage of the battery. In the figure, 3dd13 and 3dd15 are the adjusting pipes. Please give me some suggestions.
