APPLICATION INFORMATION
general function
The TLC5617 uses a resistor string network buffered with an op amp to convert 10-bit digital data to analog
voltage levels (see functional block diagram and Figure 17). The output of the TLC5617 is the same polarity
as the reference input (see Table 1).
The output code is given by: 2 V
REFIN
CODE
