description
The TLC5620C and TLC5620I are quadruple 8-bit voltage output digital-to-analog converters (DACs) with
buffered reference inputs (high impedance). The DACs produce an output voltage that ranges between either
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 5 V. A power-on reset function is incorporated to ensure repeatable start-up
conditions.
Digital control of the TLC5620C and TLC5620I are 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 DAC registers are 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 TLC5620C is characterized for operation from 0°C to 70°C. The TLC5620I is characterized
for operation from – 40°C to 85°C. The TLC5620C and TLC5620I do not require external trimming.
