DESCRIPTION
The TLV5636 is a 12-bit
voltage output DAC with a flexible 4-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 programmable settling time of the DAC allows the designer to optimize speed vs power dissipation. With its on-chip programmable precision
voltage reference, the TLV5636 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-p...
