description

The TLV5614 is a quadruple 12-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 TLV5614 is

programmed with a 16-bit serial word comprised

ofaDACaddress, individualDACcontrolbits, and

a 12-bit DAC value. The device has provision for

two supplies: one digital supply for the serial

interface (via pins DV

and DGND), and one for

the DACs, reference buffers, and output buffers (via pins AV

and AGND). Each supply is independent of the

other, and can be any value between 2.7 V and 5.5 V. The dual supplies allow a typical application where the

DAC will be controlled via a microprocessor operating on a 3 V supply (also used on pins DV and DGND),

with the DACs operating on a 5 V supply. Of course, the digital and anlog supplies can be tied together.

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. A rail-to-rail output stage and a power-down mode

makes it ideal for single voltage, battery based applications. 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 REFINAB and REFINCD

terminals to reduce the need for a low source impedance drive to the terminal. REFINAB and REFINCD allow

DACs A and B to have a different reference voltage then DACs C and D.

The TLC5614 is implemented with a CMOS process and is available in a 16-terminal SOIC package. The

TLV5614C is characterized for operation from 0°C to 70°C. The TLV5614I is characterized for operation from

–40°C to 85°C.
