Product Summary
The TLV5638CDR is a dual 12-bit voltage output DAC with a flexible 3-wire serial interface. The serial interface allows glueless interface to TMS320 and SPIE, QSPIE, and MicrowireE serial ports. TLV5638CDR is programmed with a 16-bit serial string containing 4 control and 12 data bits. The resistor string output voltage is buffered by a x2 gain rail-to-rail output buffer. The buffer features a Class AB output stage to improve stability and reduce settling time. The programmable settling time of the DAC allows the designer to optimize speed vs power dissipation. With its on-chip programmable precision voltage reference, the TLV5638CDR simplifies overall system design. Because of TLV5638CDR ability to source up to 1 mA, the reference can also be used as a system reference. Implemented with a CMOS process, the device is designed for single supply operation from 2.7 V to 5.5 V. TLV5638CDR is available in an 8-pin SOIC package to reduce board space in standard commercial, industrial, and automotive temperature ranges. TLV5638CDR is also available in JG and FK packages in the military temperature range.
