TDA7850 Typical application Circuitry

TDA7850

The TDA7850 is a powerful car radio amplifier from Microelectronics. It's a four-channel BTL (Bridge-Tied Load) output amplifier, designed to deliver high-quality audio. The precise connection of TDA7850 in your circuit can depend heavily on your specific application, but here's a general guide to connecting the TDA7850:

1. Power Supply: Connect the VCC pin to your power supply, ensuring it's within the rated operating voltage (14.4V typically). The power ground (PGND) pins should be linked to the ground of your power source.

2. Input Audio Signals: Four input channels, IN1, IN2, IN3, and IN4, are accepted by the amplifier. Connect these pins to your audio source.

3. Output Connections: The outputs are delivered through four pins, OUT1, OUT2, OUT3, and OUT4. Each output pin should be connected to a loudspeaker. The TDA7850 has a BTL output configuration, which means that each loudspeaker should be connected between an output pair (for example, OUT1+ and OUT1-).

4. Standby and Mute: The STAY (standby) and MUTE pins are used to control the operating state of the TDA7850. Pull the STAY pin high to switch on the amplifier and pull the MUTE pin high to unmute the amplifier. These pins can be controlled by a microcontroller or other logic signal.

5. Diagnostics: The DRAG pin can be used to monitor the state of the amplifier. This pin can be linked to a microcontroller to read fault states and other operational information.

6. Decoupling Capacitors: It is crucial to place decoupling capacitors close to the VCC and ground pins to reduce noise.

This is a high-level guide for connecting the TDA7850 in a circuit. The TDA7850 data sheet has the most accurate and complete information, so always refer to it. The amplifier's suggested operation and circuit design will be covered in great depth in the data sheet. Furthermore, remember to adhere to good circuit design practices and follow safety guidelines when working with electronics.
