Answer I just want to give some datasheet of DAC0832

The basic principle of D/A conversion is R - 2 R network: pin alignment of DAC0832 DAC0832 is D/A conversion chip of 8 resolution. Which is complete compatible with microprocessor.The DA chip with the advantages of its low cost, simple interface, convert and control easy , is widely used in the MCU application system.D/A converter consists of eight input latch, 8-bit DAC registers, 8 D/A conversion circuit and control circuit. Its main feature parameters is as follows: * eight resolution; * current stable time:1 us; * can be single buffer, double buffer or direct digital input; * need to adjust the linearity under the full scale; * a single power supply (+ 5 v ~ + 15 v); * low power consumption, 200 mw. The relationship between input and output of DAC0832: The work way of DAC0832: According to the data of different control mode of DAC0832 latch and DAC register, there are three kinds of DAC0832 works: direct method, single buffer method and double buffering method. Basic application of DAC0832 (converts the output current to a voltage) :
