TLV5621 说明
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.
