Product specification
TDA8714
CHARACTERISTICS
VCCA = V7 to V6 = 4.75 to 5.25 V; VCCD = V18 to V17 = 4.75 to 5.25 V; VCCO = V19 and V21 to V20 = 4.75 to 5.25 V;
AGND and DGND shorted together; VCCA to VCCD = −0.25 to +0.25 V; VCCO to VCCD = −0.25 to +0.25 V;
VCCA to VCCO = −0.25 to +0.25 V; Vi(p-p) = 1.75 V; Tamb = 0 to +70 °C; typical values measured at
VCCA = VCCD = VCCO = 5 V and Tamb = 25 °C; unless otherwise specified.
