DESCRIPTION

The TLV5614IYE is a quadruple 12-bit voltage output digital-to-analog converter (DAC) with a flexible 4-wire serial

interface. The serial interface allows glueless interface to TMS320, SPI, QSPI, and Microwire serial ports. The TLV5614IYE

is programmed with a 16-bit serial word comprised of a DAC address, individual DAC control bits, 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 is 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 analog 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 TLV5614IYE is implemented with a CMOS process and is available in a 16-terminal WCS package. The TLV5614IYE

is characterized for operation from −40°C to 85°C in a wire-bonded small outline (SOIC) package.
