HTCSEMI HT5615ARZ

The HT5615A is a 10-bit voltage output digital-to-analog converter (DAC) with a buffered reference input (high impedance). The DAC has an output voltage range that is two times the reference voltage, and the DAC is monotonic. The device is simple to use, running from a single supply of 5V. A power-on-reset function is incorporated to ensure repeatable start-up conditions. Digital control of the HT5615A is over a three-wire serial bus that is CMOS compatible and easily interfaced to industry standard microprocessor and microcontroller devices. The device receives a 16-bit data word to produce the analog output. The digital inputs feature Schmitt triggers for high noise immunity. Digital communication protocols include the SPI, QSPI, and Microwire standards. The 8-terminal small-outline D package allows digital control of analog functions in space-critical applications. The HT5615 is characterized for operation from 0°C to +70°C. The HT5615A is characterized for operation from –40°C to ±85°C.
