APPLICATION INFORMATION
general function
The TLV5626 is a dual 8-bit, single supply DAC, based on a resistor string architecture. It consists of a serial
interface, a speed and power-down control logic, a programmable internal reference, a resistor string, and a
rail-to-rail output buffer.
The output voltage (full scale determined by reference) is given by:
2REF
CODE
0x1000
[V]
Where REF is the reference voltage and CODE is the digital input value in the range 0x000 to 0xFF0.Bits 3 to
0 must be set to zero. A power-on reset initially puts the internal latches to a defined state (all bits zero).
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 TLV5626 to TMS320, SPI
, and Microwire.
