Preliminary specification
TDA8767
CHARACTERISTICS
VCCA = V2 to V44, V9 to V10, V3 to V4 and V41 to V40 = 4.75 to 5.25 V; VCCD = V37 to V38 and V15 to V17 = 4.75 to 5.25 V;
VCCO = V33 to V34 = 3.0 to 5.25 V; AGND and DGND shorted together; Tamb = 0 to +70 °C; typical values measured at
VCCA = VCCD = 5 V and VCCO = 3.3 V; Vi(p-p) − Vi(p-p) = 2.0 V; CL = 15 pF and Tamb = 25 °C; unless otherwise specified.
