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
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 2.7 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
DD
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.
