TDA7560H 개요
A power amplifier is an electronic device that increases the amplitude of an audio signal to drive speakers. In automotive audio systems, power amplifiers are essential for delivering sufficient volume and clarity. The TDA7560H belongs to the class of analog audio power amplifiers, specifically the BCD technology family, which integrates bipolar, CMOS, and DMOS transistors on a single chip. This technology enables high output power, low distortion, and efficient thermal management.
Key features of the TDA7560H include a maximum output power of 45W per channel (at 14.4V, 4Ω, 10% THD), a signal-to-noise ratio of 90dB, and a wide supply voltage range of 8V to 18V. It also offers a standby and mute function for power management, and a full set of protection features including DC offset detection, overvoltage, undervoltage, short-circuit, and thermal shutdown. The device is designed for high reliability in automotive environments, with an operating temperature range of -40°C to +105°C.
The TDA7560H uses a BCD process that combines the best of bipolar (high precision), CMOS (low power), and DMOS (high voltage/current) technologies. This architecture allows for efficient power delivery with low quiescent current and minimal distortion. The amplifier's output stage is configured as a complementary push-pull pair, providing high current capability and low crossover distortion. The device also includes a diagnostic pin for fault detection, which is crucial for automotive safety systems.
Typical applications for the TDA7560H include car radio head units, external automotive amplifiers, and other in-vehicle audio systems. Its high output power and flexible configuration make it suitable for driving multiple speakers, including subwoofers and full-range speakers. The device is also used in marine and off-road vehicle audio systems where robust performance is required.
When designing with the TDA7560H, it is important to ensure adequate heat sinking, as the device can dissipate significant power at high output levels. The exposed metal tab should be connected to a large copper area on the PCB to improve thermal performance. Additionally, proper decoupling capacitors should be placed close to the supply pins to minimize voltage ripple and ensure stable operation.

설계 노트
The TDA7560H can dissipate significant power at high output levels. For example, at 45W per channel into 4Ω, the power dissipation can exceed 20W. The exposed metal tab must be connected to a large copper area on the PCB, and a heat sink with a thermal resistance of less than 5°C/W is recommended for continuous operation. Ensure adequate airflow in the enclosure to prevent thermal shutdown.
Place decoupling capacitors (100nF ceramic and 1000uF electrolytic) close to the VS pin to minimize voltage ripple and ensure stable operation. The ground pins should be connected to a solid ground plane to reduce noise and improve thermal performance. Keep input signal traces short and shielded to avoid interference.
Do not operate the TDA7560H without a load connected to the outputs, as this can cause oscillation and damage the device. Ensure the standby and mute pins are properly controlled to avoid pop noise during power-up and power-down. The diagnostic pin should be monitored by the microcontroller to detect faults such as short circuits or overvoltage.
