This is a DIY car amplifier circuit diagram using tda2004 IC. It’s a 12-volt audio amplifier circuit diagram. This circuit can make 25 watts in bridge mode. In stereo mode, this IC can make 10+10 watts. We can use a 12-volt battery to run this circuit. For this, we can use it in the car.
The TDA2004 is an integrated circuit (IC) primarily designed as a Class B dual audio power amplifier in an 11-pin Multiwatt package, most commonly used in car radio applications.
Key Features and Specifications
-
Type: Class B Dual Audio Power Amplifier.
-
Application: Specifically designed for car radios and power booster amplifiers.
-
Power Output: Typically 10W + 10W stereo output (or up to 12W per channel) into a 2\Omega load at 14.4V supply, or 6.5W per channel into a 4\Omega load. It can drive very low impedance loads, down to 1.6\Omega.
-
High Current Capability: Provides a high output peak current (up to 3.5A repetitive).
-
Operating Voltage: The typical operating supply voltage (V_S) is from 8V to 18V.
-
Low Component Count: It allows for compact applications due to the very low number of external components required.
Built-in Protection Systems: It includes several protections for high reliability:
-
Output AC Short Circuit to Ground
-
Overrating Chip Temperature (Thermal Shut-down)
-
Load Dump Voltage Surge
-
Fortuitous Open Ground
-
Very Inductive Loads
-
Polarity Inversion
Pin Configuration: It is typically an 11-pin package (Multiwatt-11), with pins including:
-
Non-Inverting Input 1
-
Inverting Input 1
-
SVRR (Supply Voltage Rejection Ratio)
-
Inverting Input 2
