description
The TLC5628C and TLC5628I are octal 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 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 TLC5628C and TLC5628I are over a simple three-wire serial bus that is CMOS compatible
and easily interfaced to all popular microprocessor and microcontroller devices. The 12-bit command word
comprises eight bits of data, three 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 16-terminal small-outline (D) package allows digital control of analog functions in space-critical
applications. The TLC5628C is characterized for operation from 0°C to 70°C. The TLC5628I is characterized
for operation from – 40°C to 85°C. The TLC5628C and TLC5628I do not require external trimming.
