TDA8595TH/N2S,112

Overview

The TDA8595TH/N2S,112 is a complementary quad Bridge Tied Load (BTL) audio power amplifier manufactured using BCDMOS technology. It integrates four independent amplifiers and supports both legacy mode and I2C-bus mode with 3.3 V and 5 V compliance. The device features three hardware-programmable I2C addresses and drives 4 Ω or 2 Ω loads. Key electrical parameters include a supply voltage range of 8 V to 18 V, a typical quiescent current of 270 mA at no load, and an output power of up to 64 W into a 2 Ω load. Total harmonic distortion is typically 0.01% at 1 W output.

Feature Summary

• Supports legacy mode and I2C-bus mode with programmable gain and diagnostic levels
• Features independent short-circuit protection per channel and speaker fault detection
• Includes DC and AC load detection capabilities for automatic gain selection
• Provides fully programmable thermal pre-warning and clip detection via I2C

Applications

• Automotive audio systems requiring robust diagnostics
• Multi-channel car radio power amplification
• High-performance vehicle infotainment setups

Procurement Notes

Verify the specific ordering suffix matches the required package type and marking configuration. Confirm that the component meets AEC-Q100 qualification standards if automotive application is intended. Ensure the design accommodates the HSOP36 package dimensions and thermal requirements specified in the datasheet.

Selection Notes

Select this component when a quad BTL amplifier with comprehensive I2C-based diagnostics is required. It is suitable for designs needing independent channel protection and load detection. Consider the HSOP36 package for heatsink integration. Verify compatibility with the system's I2C bus voltage levels and address configuration.

Part Context

This part belongs to the TDA8595 family of I2C-controlled power amplifiers. The TH variant specifically denotes the HSOP36 plastic heatsink small outline package. This family is designed for automotive applications, offering high reliability and extensive diagnostic feedback through digital interfaces.

Replacement Considerations

Check for direct substitutes within the TDA8595 family such as the TDA8595J or TDA8595SD, noting differences in package type. Ensure any replacement maintains the same pinout compatibility and electrical specifications for the target application.
