APPLICATION INFORMATION
general function
The TLV5614 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:
2 REF0x1000[V]
Where REF is the reference voltage and CODE is the digital input value within the range of 0x000 to 0xFFF.
A power-on reset initially resets the internal latches to a defined state (all bits zero).
serial interface
Explanation of data transfer: First, the device has to be enabled with CS set to 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
updates the voltage output to the new level.
The serial interface of the TLV5614 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 (DSP or microcontroller). The interface is compatible with the TMS320 family. Figure 15 shows
an example with two TLV5614s connected directly to a TMS320 DSP.
