The TLV5621I 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 since it operates from a single supply of 2.7 V to 5.5 V. A power-on reset function is incorporated to provide repeatable start-up conditions. A global hardware shut-down terminal and the capability to shut down each individual DAC with software are provided to minimize power consumption.

Digital control of the TLV5621I is over a simple 3-wire serial bus that is CMOS compatible and easily interfaced to all popular microprocessor and microcontroller devices. A TLV5621I 11-bit command word consists of eight bits of data, two DAC select bits, and a range bit for selection between the times one or times two output range. The TLV5621I digital inputs feature Schmitt triggers for high noise immunity. The DAC registers are double buffered which allows a complete set of new values to be written to the device, and then under control of the HWACT signal, all of the DAC outputs are updated simultaneously.

The 14-terminal small-outline (D) package allows digital control of analog functions in space-critical applications. The TLV5621I does not require external trimming. The TLV5621I is characterized for operation from -40°C to 85°C.
