Digital-to-analog Converters, TLC5620CN, Texas Instruments

The TLC5620CN is a quadruple 8-bit voltage-output digital-to-analog converter (DAC) with buffered (high-impedance) reference inputs. It produces an output voltage ranging from either one or two times the reference voltage to GND and is monotonic. The device operates from a single 5 V supply and includes a power-on reset for repeatable start-up conditions. Digital control is provided via a simple three-wire CMOS-compatible serial interface, making it easy to connect to most microprocessors and microcontrollers. The 11-bit command word consists of eight data bits, two DAC-select bits, and one range bit, which selects between the ×1 or ×2 output range. The DAC registers are double-buffered, allowing new values to be loaded and then simultaneously updated on all outputs through the LDAC control. Schmitt-trigger digital inputs provide high noise immunity.
