MAX522CPA+ Datasheet PDF - Maxim Integrated

●The MAX522CPA+ is a dual, 8bit, voltage output serial digital to analogue converter (DAC) in 8 pin DIP package. The DAC is "inverted" R-2R ladder network using complementary switches that convert 8bit digital inputs into equivalent analogue output voltages in proportion to the applied reference voltage. It has one reference input which is shared by DAC A and DAC B. The device includes output buffer amplifiers for both DACs and input logic for simple microprocessor (µP) and CMOS interfaces. This device is used in digital gain and offset adjustment, programmable current source, programmable voltage source, power-amp bias control and VCO tuning.
