TLV5614 概述

The TLV5614 is a quadruple 12-bit voltage output digital-to-analog converter (DAC) with a flexible 4-wire serial interface. The 4-wire serial interface allows glueless interface to TMS320, SPI, QSPI, and Microwire serial ports. The TLV5614 is programmed with a 16-bit serial word comprised of a DAC address, individual DAC control bits, and a 12-bit DAC value.

The TLV5614 is implemented with a CMOS process and is available in a 16-terminal SOIC package. The TLV5614C is characterized for operation from 0°C to 70°C. The TLV5614I is characterized for operation from –40°C to 85°C.
