Pinout Diagram: TDA2030, TDA2050, TDA7266, TDA7265, TDA7294
TDA2030 Pinout Diagram
Here, you can see the Pinout Diagram of IC TDA2030.
The TDA2030 is a versatile audio amplifier IC and it is very popular for its efficiency and reliability in low-power audio applications. It can deliver up to 14 watts of output power in mono (single-channel) mode when powered with a ±14V supply and connected to a 4-ohm speaker.
For higher output needs, the TDA2030 can be configured in a bridge mode using two ICs, which provide up to 35 watts of power.
The TDA2030 is designed to operate with either a single or dual power supply, typically in the range of ±12V to ±18V for dual-supply configurations, making it flexible for various amplifier designs.
The TDA2030 is a 5-pin IC housed in a TO-220 package. Here are the details of each pin described below,
- Pin 1 is the inverting input (-), where the audio signal is usually fed through a resistor and capacitor network to set the amplifier's gain.
- Pin 2 is the non-inverting input (+), which is typically connected to ground in single-supply configurations or to a reference voltage in dual-supply setups.
- Pin 3 is the negative power supply (V−) and is connected to the negative voltage rail in dual-supply mode or to ground in single-supply applications.
- Pin 4 is the output pin, delivering the amplified audio signal to the speaker, often through a capacitor or low-pass filter to ensure clean output.
- Pin 5 is the positive power supply (V+), connected to the positive voltage rail. This clear pin configuration makes the TDA2030 easy to implement in both single and dual power supply designs.
TDA2050 Pinout Diagram
Here, you can see the Pinout Diagram of IC TDA2050
The TDA2050 is a high-performance audio amplifier IC. It has the similar pinout and function to the TDA2030 but with higher output power and improved audio characteristics. It is widely used in hi-fi audio systems, powered speakers, and DIY amplifier projects due to its robustness, sound quality, and ease of use.
The TDA2050 can deliver up to 32W of output power in mono mode when operated with a ±18V dual power supply and an appropriate heat sink. In a bridge configuration using two TDA2050 ICs, it can produce up to 50–60W, making it suitable for driving larger speakers or subwoofers.
The TDA2050 is designed to operate with either single or dual power supplies, typically in the range of ±4.5V to ±25V for dual supply, giving it flexibility in various amplifier configurations.
