TLV5623ID

The TLV5623ID is a 8-bit voltage output Digital-to-analog Converter (DAC) with a flexible 4-wire serial interface. The 4-wire serial interface allows glueless interface to TMS320, SPI, QSPI and MICROWIRE serial ports. The TLV5623 is programmed with a 16-bit serial string containing 4 control and 8 data bits. Developed for a wide range of supply voltages, the TLV5623 can operate from 2.7 to 5.5V. The resistor string output voltage is buffered by x2 gain rail-to-rail output buffer. The buffer features a Class AB output stage to improve stability and reduce settling time. The settling time of the DAC is programmable to allow the designer to optimize speed versus power dissipation. The settling time is chosen by the control bits within the 16-bit serial input string. A high-impedance buffer is integrated on the REFIN terminal to reduce the need for a low source impedance drive to the terminal.
