TDA8552T/N1,518

Overview

The TDA8552T is a two-channel audio power amplifier delivering 2 x 1.4 W into an 8 Ω load at 5 V supply. It features Bridge-Tied Load (BTL) architecture with digital volume control and headphone sensing. The device includes standby/mute logic, internal feedback resistors, and protection against short circuits and thermal overload. Gain selection is configurable via the GAINSEL pin for 20 or 30 dB maximum gain. Volume is adjusted using UP/DOWN pulses, supporting auto-repeat functionality.

Feature Summary

Integrated digital volume control with up/down pulse interface and auto-repeat function
Automatic switching between BTL loudspeaker mode and Single-Ended headphone mode upon jack insertion
Low saturation voltage output stage with high supply voltage ripple rejection
Built-in protections including thermal shutdown and short-circuit safety to ground, VDD, and across the load

Applications

Portable consumer products
Notebook computers
Communication equipment

Procurement Notes

Verify the specific ordering suffix matches the required package type. The TDA8552T designation corresponds to the SO20 plastic small outline package. Confirm that the N1,518 suffix aligns with the intended manufacturing version and environmental compliance standards specified in the current product specification before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel BTL amplifier with integrated digital volume control is required. The device supports both push-button and microcontroller-driven volume adjustment. Ensure the application utilizes a 5 V supply for optimal 1.4 W per channel performance. Consider the SO20 package thermal characteristics if operating near maximum ambient temperature limits.

Part Context

The TDA8552T belongs to the TDA855x series of audio amplifiers from NXP Semiconductors. This family focuses on low-component-count solutions for portable electronics. The TDA8552T specifically provides stereo output capabilities with advanced control features like headphone detection, distinguishing it from mono variants or simpler amplifier models within the broader portfolio.
