TLV5614IYZ
SBAS401 – DECEMBER 2006
The TLV5614IYZ is a 12-bit, single-supply DAC based on a resistor string architecture. The device consists of a
serial interface, speed and power-down control logic, a reference input buffer, a resistor string, and a rail-to-rail
output buffer.
The output voltage (full-scale determined by external reference) is given by:
where REF is the reference voltage and CODE is the digital input value within the range of 010 to (2
n – 1), where
n = 12 (bits). The 16-bit data word, consisting of control bits and the new DAC value, is described in the data
format section. A power-on reset initially resets the internal latches to a defined state (all bits '0').
Data transfer occurs in this manner: First, the device must be enabled with CS set low. Then, a falling edge of
FS starts shifting the data bit-per-bit (starting with the MSB) to the internal register on the falling edges of SCLK.
After 16 bits have been transferred or FS rises, the content of the shift register is moved to the DAC latch, which
then updates the voltage output to the new level.
The serial interface of the TLV5614IYZ can be used in two basic modes:
Four-wire (with chip-select)
Three-wire (without chip-select)
Using chip-select (four-wire mode), it is possible to have more than one device connected to the serial port of
the data source (a DSP or microcontroller). The interface is compatible with the TMS320 DSP family. Figure 15
shows an example with two TLV5614IYZs connected directly to a TMS320 DSP.
Figure 15. TMS320 Interface
If there is no need to have more than one device on the serial bus, then CS can be tied low. Figure 16 shows an
example of how to connect the TLV5614IYZ to a TMS320, SPI, or Microwire port using only three pins.
