TLV5620ID

The TLV5620ID is a quadruple 8-bit voltage output Digital-to-analog Converter (DAC) with buffered reference inputs (high impedance). The DAC produces an output voltage that ranges between either one or two times the reference voltages and GND and the DAC is monotonic. The device is simple to use, because it runs from a single supply of 3 to 3.6V. A power-on reset function is incorporated to ensure repeatable start-up conditions. Digital control of the TLV5620C is over a simple 3-wire serial bus that is CMOS compatible and easily interfaced to all popular microprocessor and microcontroller devices. The 11-bit command word comprises 8-bit of data, two DAC select bits and a range bit, the latter allowing selection between the times 1 or times 2 output range. The DAC registers are double buffered, allowing a complete set of new values to be written to the device, then all DAC outputs update simultaneously through control of LDAC.
