description
The TLV5623 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 pro-
grammed with a 16-bit serial string containing 4
control and 12 data bits. Developed for a wide
range of supply voltages, the TLV5623 can
operate from 2.7 V to 5.5 V.
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 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.
Implemented with a CMOS process, the TLV5623 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 TLV5623C is characterized for operation from 0
°C
to 70
°C. The TLV5623I is characterized for operation from –40°C to 85°C.
