description
The TLV5624 is a 8-bit voltage output DAC with a flexible 4-wire serial interface. The serial interface allows
glueless interface to TMS320 and SPI, QSPI, and Microwireserial ports. It is programmed with a 16-bit
serial string containing 4 control and 8 data bits.
The resistor string output voltage is buffered by a x2 gain rail-to-rail output buffer. 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 TLV5624 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 and 8-pin MSOP package to reduce board space in standard commercial and industrial
temperature ranges.
