† Component qualification in accordance with JEDEC and industry
standards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification
testing should not be viewed as justifying use of this component
beyond specified performance and environmental limits.

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.
