Preliminary specification
TDA8765
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 85 °C; typical values measured at
VCCA = VCCD = 5 V and VCCO = 3.3 V, Tamb = 25 °C, VI(p-p) − VI(p-p) = 2.0 V and CL = 10 pF; unless otherwise specified.
