The TLC5617 and TLC5617A are dual 10-bit
voltage output digital-to-analog converters (DAC)
with buffered reference inputs (high impedance).
The DACs have an output voltage range that is
two times the reference voltage, and the DACs are
monotonic. The devices are simple to use,
running from a single supply of 5 V. A power-on
reset function is incorporated to ensure repeat-
able start-up conditions.

Digital control of the TLC5617 is over a 3-wire CMOS compatible serial bus. The device receives a 16-bit word
for programming and producing the analog output. The digital inputs feature Schmitt triggers for high noise
immunity. Digital communication protocols include the SPI™, QSPI™, and Microwire™ standards.
Two versions of this device are available. The TLC5617 does not have any internal state machine and is
dependent on all external timing signals. The TLC5617A has an internal state machine that will count the
number of clocks from the falling edge of CS and then updates and disables the device from accepting further
data inputs. The TLC5617A is recommended for TMS320 and SPI processors and the TLC5617 is
recommended only for use in SPI or 3-wire serial port processors. The TLC5617A is backward compatible and
designed to work in TLC5617 designed systems.
The 8-terminal small-outline D package allows digital control of analog functions in space-critical applications.
The TLC5617C is characterized for operation from 0°C to 70°C. The TLC5617I is characterized for operation
from – 40°C to 85°C.
