Product data sheet
8.1 Voltage reference
Table 3.
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.
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 V
