12 W car radio power amplifier

General Description

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 VP= 14,4 V, an output power of 7 W can be delivered into a 4 Ω load and 12 W into 2 Ω. 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.

Recording/playback and 2 W audio power amplifier TDA1016

GENERAL DESCRIPTION:

The TDA1016 is a monolithic integrated audio power amplifier, preamplifier and A.L.C. circuit designed for applications in radio-recorders and recorders. The wide supply voltage range makes this circuit very suitable for d.c. and a.c. apparatus. The circuit incorporates the following features:

Features:

• Power amplifier/monitor amplifier
• Preamplifier/record and playback amplifier
• Automatic Level Control (A.L.C.) circuit
• Voltage stabilizer
• Short-circuit (up to 12 V a.c.) and thermal protection

How To Build A Subwoofer Box

How to Design a Subwoofer Box

In this video I teach you how to design a subwoofer enclosure box using some of the leading design software. I also show you what math equations to use and how to design using a variable dimension for one of the sides of your sub enclosure. This can be used for speakers as well. Then you just need to build, grab an amplifier and your flexing away!
