Product specification
TDA8703
CHARACTERISTICS
VCCA = V7 − V3 = 4.5 V to 5.5 V; VCCD = V18 − V20 = 4.5 V to 5.5 V; VCCO = V19 − V20 = 4.5 V to 5.5 V; AGND and
DGND shorted together; VCCA − VCCD = −0.5 V to +0.5 V; VCCO − VCCD = −0.5 V to +0.5 V;
VCCA − VCCD = −0.5 V to +0.5 V; Tamb = 0 °C to +70 °C; unless otherwise specified (typical values measured at
VCCA = VCCD = VCCO = 5 V and Tamb = 25 °C).
