TLV5637

10 位 1us DAC，具有串行输入、双路 DAC、可编程内部参考和稳定时间

The is a dual 10-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 2 control and 10 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 versus power dissipation. With its on-chip programmable precision voltage reference, the TLV5637 simplifies overall system design.

Because of its ability to source up to 1mA, the reference can also be used as a system reference. Implemented with a CMOS process, the device is designed for single supply operation from 2.7V to 5.5V. It is available in an 8-pin SOIC package to reduce board space in standard commercial and industrial temperature ranges.
