The analog inputs self-bias to VD/3. This common-mode voltage can be overdriven externally by a low impedance source by ±300 mV (differential drive, gain = 1). 4 AC power dissipation measured with rated encode and a 10 MHz analog input at 0.5 dBFS, CLOAD = 5 pF. 5 DC power dissipation measured with rated encode and a dc analog input (outputs static, IVDD = 0). 6 In power-down state, IVDD = ±10 µA typical.
