Product specification
Satellite sound circuit with noise reduction
TDA8740; TDA8740H
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
Notes
1. All voltages referenced to ground pins 9 and 34 (4 and 30).
2. All voltages referenced to ground pins 9 and 34 (4 and 30). These voltages must not exceed VP or maximum value
at any time.
THERMAL CHARACTERISTICS
DC CHARACTERISTICS
All voltages referenced to ground at pins 9 and 34 (4 and 30). Measured in test circuit Fig.4; VP =12V; Tamb =25 °C;
∆fM = ∆fS1 = ∆fS2 = 0 kHz (no modulation); fOM = 6.5 MHz; fOS1 = 7.02 MHz; fOS2 = 7.20 MHz; HF level at pin 18 (14):
40 mV (RMS); HF level at selected secondary inputs: 20 mV (RMS); MCS = logic 0 [V7 (V2)=0V];
SCD = logic 0 [V11 (V6) = 0 V]; unless otherwise specified.
