Philips Semiconductors
The TDA1020 is a monolithic integrated 12 W audio amplifier in a 9-lead single in-line (SIL) plastic package. The device
is primarily developed as a car radio amplifier. At a supply voltage of V
into a 4
To avoid interferences and car ignition signals coming from the supply lines into the IC, frequency limiting is used beyond
the audio spectrum in the preamplifier and the power amplifier.
The maximum supply voltage of 18 V makes the IC also suitable for mains-fed radio receivers, tape recorders or record
players. However, if the supply voltage is increased above 18 V (< 45 V), the device will not be damaged (load dump
protected). Also a short-circuiting of the output to ground (a.c.) will not destroy the device. Thermal protection is built-in.
As a special feature, the circuit has a low stand-by current possibility.
The TDA1020 is pin-to-pin compatible with the TDA1010.
