TLV5638 概述

The TLV5638 is a dual 12-bit voltage output DAC with a flexible 3-wire serial interface. The serial interface allows glueless interface to TMS320 and SPITM, QSPITM, and MicrowireTM serial ports. It is programmed with a 16-bit serial string containing 4 control and 12 data bits.

Because of its ability to source up to 1 mA, the reference can also be used as a system reference. Implemented with a CMOS process, the TLV5638 is designed for single supply operation from 2.7 V to 5.5 V. The TLV5638 is available in an 8-pin SOIC package to reduce board space in standard commercial, industrial, and automotive temperature ranges. The TLV5638 is also available in JG and FK packages in the military temperature range.
