DESCRIPTION
The TLV5614IYZ 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 TLV5614IYZ 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_DD and DGND), and one for the DACs, reference buffers, and output buffers (via pins AV_DD and
AGND). Each supply is independent of the other, and can be any value between 2.7V and 5.5V. The dual
supplies allow a typical application where the DAC is controlled via a microprocessor operating on a 3V supply
(also used on pins DV_DD and DGND) with the DACs operating on a 5V supply. Of course, the digital and analog
supplies can also be tied together.
The resistor string output voltage is buffered by a 2x 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 DAC settling time is programmable,
allowing the designer to optimize speed versus power dissipation. 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 than DACs C and D.
The TLV5614IYZ is built with a CMOS process and is available in a 16-terminal bumped die (wafer chip scale)
package. It is characterized for operation from –40°C to +85°C in a wire-bonded, small outline (SOIC) package.
