APPLICATION INFORMATION
general function
The TLC5618 uses a resistor string network buffered with an op amp to convert 12-bit digital data to analog
voltage levels (see functional block diagram and Figure 17). The output is the same polarity as the reference
input (see Table 1).
The output code is given by: 2 V
