Product specication
Triple 8-bit video Digital-to-Analog
Converter (DAC)
TDA8771A
Notes
1. Minimum and maximum data of current and power consumption are measured in worse case conditions: for
minimum data, all digital inputs are at logic level 0 while for maximum data, all digital inputs are at logic level 1.
2. VO is directly proportional to VREF.
