The TLC5615 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 5 V. A power-on-reset function is incorporated to ensure repeatable start-up conditions. Digital control of the TLC5615 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 SPITM, QSPITM, and MicrowireTM standards. The 8-terminal small-outline D package allows digital control of analog functions in space-critical applications. The TLC5615C is characterized for operation from 0C to 70C. The TLC5615I is characterized for operation from 40C to 85C.
