description  
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  
SPI , QSPI , and Microwire serial ports. It 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 TLV5638 simplifies overall system design.  
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 device is designed for single supply operation from 2.7 V to 5.5 V. It is available in  
an 8-pin SOIC package to reduce board space in standard commercial, industrial, and automotive temperature  
ranges. It is also available in JG and FK packages in the military temperature range.
