This paper introduces a sort of program-controlled-gain technology, which makes use of DAC0832. The amplifier has good control and linear characteristic.
The principle of the most significant bits digital decoder-13 bits DAC is described in detail, and the gaincontrolledamplifier is theoretically analysed.
