TDA8560Q/N1C,112

Overview

The TDA8560Q/N1C,112 is a Class-B stereo BTL car radio power amplifier manufactured by NXP USA Inc. It delivers up to 40 W per channel into a 2 Ω load and 25 W into a 4 Ω load at 10% THD with a 14.4 V supply. The device operates on a 6 V to 18 V supply voltage and features a fixed closed-loop gain of 40 dB. It utilizes a 13-lead DBS13P single-in-line package.

Feature Summary

• Comprehensive protection against short circuits, thermal overload, and reverse polarity
• Mode select switch supporting operating, mute, and standby states
• Low quiescent current in standby mode

Applications

• Car radio power amplification
• Automotive audio systems
• BTL stereo amplifier configurations

Procurement Notes

Verify the exact ordering suffix and revision level against the official NXP datasheet before procurement. Confirm that the component meets the required automotive environmental standards and package specifications. Ensure compatibility with existing circuit designs regarding pinout and thermal management requirements.

Selection Notes

Select this component for applications requiring high output power in a compact form factor. Consider the fixed gain and diagnostic capabilities when designing the signal chain. Evaluate thermal resistance and heat sinking needs based on the expected power dissipation and ambient temperature conditions.

Part Context

This part belongs to the TDA856x series of integrated circuits designed for automotive audio applications. It represents a solution for high-power stereo amplification with built-in diagnostics and protection features suitable for harsh vehicle environments.

Replacement Considerations

Check for direct substitutes within the TDA856x family or other NXP automotive amplifier lines. Verify pin compatibility and electrical specifications before considering alternative components.

FAQ

How does the diagnostic output function?

Pin 12 serves as an open-collector diagnostic output. It goes low during dynamic distortion (clipping), short-circuit conditions, or when the virtual junction temperature reaches 150 °C.

What is the purpose of the mode select switch?

The mode select switch allows control over the amplifier's state, enabling operating, mute, or standby modes to manage power consumption and prevent switch-on plops.
