8. Functional description

This triple 10-bit video DAC is designed to convert digital input signals into analog output

currents. All inputs (clock, data, blank and sync) must be TLL levels.

8.1 Voltage reference

The voltage reference input to pin VREF should be 1.21 V. For correct operation, a 100 nF

capacitor should be connected between pin VREF and pin VDDA.
