DAC0800 Digital To Analog Converters TH IC
The DAC0800 series are monolithic 8-bit high-speed current-output digital-to-analog converters (DAC) featuring typical settling times of 100 ns. When used as a multiplying DAC, monotonic performance over a 40 to 1 reference current range is possible. The DAC0800 series also features high compliance complementary current outputs to allow differential output voltages of 20 Vp-p with simple resistor loads. The reference-to-full-scale current matching of better than ±1 LSB eliminates the need for full-scale trims in most applications, while the non linearities of better than ±0.1% over temperature minimizes system error accumulations.
The noise immune inputs will accept a variety of logic levels. The performance and characteristics of the device are essentially unchanged over the ±4.5V to ±18V power supply range and power consumption at only 33 mW with ±5V supplies is independent of logic input levels.

Applications:
- Analog signal generation in microcontroller‑based systems — converting digital data (e.g. from a microcontroller or DSP) into analog voltage or current for further signal processing.
- Interfacing digital processors with analog devices (e.g. providing analog control voltages for actuators, analog outputs for measurement systems).
- Audio waveform generation or low‑resolution audio output in embedded audio projects (especially where 8‑bit resolution and moderate speed suffice).
- Sensor interfacing and data acquisition systems where digital sensor data must be converted to analog for analog‑domain processing or output.
- Driving analog actuators or analog control circuits in industrial automation or instrumentation (e.g. analog control loops, analog monitoring).
- Educational electronics and prototyping — as a teaching tool and demonstration module for digital‑to‑analog conversion, DAC behavior, and mixed‑signal circuit design.
