November 1982 6 Preliminary Specification
Philips Semiconductors Product specification
12 W car radio power amplifier TDA1020
Notes
1. Measured with an ideal coupling capacitor to the speaker load.
2. Measured with a load resistor of 40 kΩ.
3. Measured according to IEC curve-A.
4. Maximum ripple amplitude is 2 V; input is short-circuited.
5. Total current when disconnecting pin 5 or short-circuited to ground (pin 9).
6. The tab must be electrically floating or connected to the substrate (pin 9).
