Internal block diagram of DACO800
The DAC0800 is an 8-bit, high speed, current output DAC with a typical settling time (conversion time) of 100 ns.
It produces complementary current output, which can be converted to voltage by using simple resistor load.
The DAC0800 require a positive and a negative supply voltage in the range of ± 5V to ±18V.
It can be directly interfaced with TTL, CMOS, PMOS and other logic families.
For TTL input, the threshold pin should be tied to ground (VLC = 0V).
The reference voltage and the digital input will decide the analog output current, which can be converted to a voltage by simply connecting a resistor to output terminal or by using an op-amp I to V converter.
