Question

1. Study how to use D/A converter regarding DAC0800 Manual (answer typed please)

   Understand the manual

Answer 1

The DAC0800 series are monolithic 8-bit high speed-current-output converters (DAC) featuring typical setting times of 100ns. When used as a multiplying DAC , monotonic performance over a DAC series also features compliance complementary current outputs to allow differential output voltages of 20 v(p-p) with simple resistor loads. The reference to fill scale current matching of better than plus or minus LSB eliminates the need for full -scale trims in most applications while the non-linearities of better then plus or minus 0.1% over temperature minimizes system error accumulations.

The noise immune inputs of the DAC0800 series will accept TTL levels with the logic threshold pin Vlc , grounded. Changing the Vlc potential will allow direct interface to other logic families. The performance and characteristics of the device are essentially unchanged over the full plus or minus 4.5V to plus or minus 18V power supply range ; power dissipation is only 33mW with plus or minus 5V supplies and is independent of the logic input states.

The DAC0800,DAC0802,DAC0800C and DAC0802C are direct replacement for the DAC-08,DAC-08A ,DAC-08C,and DAC-08H, respectively.
