TLC5617A

The TLC5617 and TLC5617A are dual 10-bit voltage output digital-to-analog converters (DAC) with buffered reference inputs (high impedance). The DACs TLC5617A 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 repeatable 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 SPIE, QSPIE, and MicrowireE 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 of TLC5617A 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.
