9-bit analog-to-digital converter for
digital video
Preliminary specification
TDA8761
CHARACTERISTICS
VCCA = V3 to V4 and V5 = 4.75 to 5.25 V; VCCD = V11 to V12 = 4.75 to 5.25 V; VCCO = V13 and V28 to V14 and
V27 = 4.4 to 5.25 V; AGND and DGND shorted together; Tamb = 0 to +70 °C; typical values measured at
VCCA = VCCD = VCCO = 5 V; Vi(p-p) = 1.5 V; CL = 15 pF and Tamb = 25 °C; unless otherwise specified.
