The 4-wire serial interface allows glueless interface to TMS320, SPI, QSPI, and Microwire serial ports. The TLV5616I is programmed with a 16-bit serial string containing 4 control and 12 data bits. Developed for a wide range of supply voltages, the TLV5616 can operate from 2.7 V to 5.5 V.
The resistor string output voltage of TLV5616I 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 settling time of the DAC is programmable to allow the designer to optimize speed versus power dissipation. The settling time of TLV5616I 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.
Implemented with a CMOS process, the TLV5616 is designed for single supply operation from 2.7 V to 5.5 V. The device is available in an 8-terminal SOIC package. The TLV5616C is characterized for operation from 0°C to 70°C. The TLV5616I is characterized for operation from 40°C to 85°C.
