TLV5638
2.7 V TO 5.5 V LOW POWER DUAL 12-BIT DIGITAL-TO-ANALOG

APPLICATION INFORMATION
serial interface
A falling edge of CS 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 CS rises, the content of the shift register is moved to the
target latches (DAC A, DAC B, BUFFER, CONTROL), depending on the control bits within the data word.
Figure 13 shows examples of how to connect the TLV5638 to TMS320, SPI
, and Microwire
.

Notes on SPI
and Microwire
: Before the controller starts the data transfer, the software has to generate a
falling edge on the pin connected to FS. If the word width is 8 bits (SPI
and Microwire
), two write operations
must be performed to program the TLV5638. After the write operation(s), the holding registers or the control
register are updated automatically on the 16
th
positive clock edge.
serial clock frequency and update rate
The maximum serial clock frequency is given by:

The maximum update rate is:

Note, that the maximum update rate is just a theoretical value for the serial interface, as the settling time of the
TLV5638 has to be considered, too.
