DESCRIPTION

The TLC5615 is a 10-bit voltage output

digital-to-analog converter (DAC) with a buffered

reference input (high impedance). The DAC has an

output voltage range that is two times the reference voltage, and the DAC is monotonic. The device is

simple to use, running from a single supply of 5V. A

power-on-reset function is incorporated to ensure

repeatable start-up conditions.

Digital control of the TLC5615 is over a three-wire

serial bus that is CMOS compatible and easily

interfaced to industry standard microprocessor and

microcontroller devices. The device receives a 16-bit

data word to produce the analog output. The digital

inputs feature Schmitt triggers for high noise

immunity. Digital communication protocols include the SPI?, QSPI?, and Microwire? standards.

The 8-terminal small-outline D package allows digital

control of analog functions in space-critical

applications. The TLC5615C is characterized for

operation from 0°C to +70°C. The TLC5615I is

characterized for operation from –40°C to +85°C.
