As the name itself points out ‘DAC0832’ is a DAC chip or Digital to Analog Conversion IC. The device is from DAC0830 series that are 8-bit members of a family of microprocessor-compatible DACs. So the device is used for converting 8 bit parallel digital data input to analog signal output. The chip is designed with CMOS technology to achieve low power consumption and low output leakage current errors.
The design also includes special circuitry that provides TTL logic input voltage level compatibility. Double buffering of the device allows outputting a voltage corresponding to one digital word while holding the next digital word. This also permits the simultaneous updating of any number of DACs.
DAC0832 also designed with silicon-chromium R-2R resistor ladder network which divides the reference current and provides the circuit with excellent temperature tracking characteristics (0.05% of Full Scale Range maximum linearity error over temperature).
Features:
- 8-bit digital-to-analog conversion.
- Double-buffered data latches.
- Parallel data input interface.
- Glitch-free output updating.
- Voltage or current output capability.
- TTL and CMOS compatible.
- High-speed operation.
- Stable analog performance.
