Preliminary specification
TDA8764
CHARACTERISTICS
The characteristics given refer to the SSOP28 package. VCCA = V3 to V4 = 4.75 to 5.25 V;
VCCD = V11 to V12 and V28 to V27 = 4.75 to 5.25 V; VCCO = V13 to V14 = 2.7 to 3.6 V; AGND and DGND shorted
together; Tamb = 0 to 70 °C; typical values measured at VCCA = VCCD = 5 V and VCCO = 3.3 V; CL = 10 pF and
Tamb = 25 °C; unless otherwise specified.
