TLC5620IDR

Product Summary

The TLC5620IDR is a quadruple 8-bit voltage output digital-to-analog converter (DAC) with buffered reference inputs (high impedance). The TLC5620CN produces an output voltage that ranges between either one or two times the reference voltages and GND, and the DACs are monotonic. The TLC5620IDR is simple to use, running from a single supply of 5 V. A power-on reset function is incorporated to ensure repeatable start-up conditions. Digital control of the TLC5620IDR is over a simple three-wire serial bus that is CMOS compatible and easily interfaced to all popular microprocessor and microcontroller devices. The 11-bit command word comprises eight bits of data, two DAC-select bits, and a range bit, the latter allowing selection between the times 1 or times 2 output range. The TLC5620IDR is double buffered, allowing a complete set of new values to be written to the device, then all DAC outputs are updated simultaneously through control of LDAC. The digital inputs feature Schmitt triggers for high noise immunity. The 14-terminal small-outline (D) package allows digital control of analog functions in space-critical applications. The TLC5620IDR is characterized for operation from 0℃ to 70℃. The TLC5620CN does not require external trimming.
