The DACs produce an output voltage that varies between one or two times the reference voltages and GND, and the DACs are monotonic. The device is simple to use, running from a single supply of 3 to 3.6 V. A power-on reset function is incorporated to ensure repeatable start-up conditions. Digital control of the TLV5628C and TLV5628I is over a simple 3-wire serial bus that is CMOS compatible and easily interfaced to all popular microprocessor and microcontroller devices. The 12-bit command word comprises 8 bits of data, 3 DAC select bits and a range bit, the latter allowing selection between the times 1 or times 2 output ran...
