The serial interface allows glueless interface to TMS320, 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.
