Video analog input interface

TDA8708B

CHARACTERISTICS

VCCA =V22 to V23 = 4.5 to 5.5 V; VCCD =V6 to V8 = 4.5 to 5.5 V; VCCO =V7 to V8 = 4.2 to 5.5 V; AGND and DGND

shorted together; VCCA to VCCD = −0.5 to +0.5 V; VCCO to VCCD = −0.5 to +0.5 V; VCCA to VCCO = −0.5 to +0.5 V;

Tamb = 0 to +70 °C; typical readings taken at VCCA =VCCD =VCCO = 5 V and Tamb =25 °C; unless otherwise speciﬁed.
