TDA8595TH/N2C,118

Overview

The TDA8595TH/N2C,118 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 operates within a supply voltage range of 8 V to 18 V. Key electrical parameters include a typical quiescent current of 400 mA at no load. Output power capabilities reach up to 64 W into a 2 Ω load and 40 W into a 4 Ω load under maximum power conditions.

Feature Summary

• Features fully programmable diagnostic levels for temperature warnings and clipping detection via the I2C-bus interface.
• Provides independent short-circuit protection per channel along with comprehensive speaker fault detection capabilities.
• Includes DC and AC load detection functions to identify connected loads such as tweeters or external boosters during start-up.
• Offers selectable gain settings and independent soft mute functionality for front and rear channels to minimize audio pops.

Applications

• Automotive audio systems requiring high-power multi-channel amplification
• Car radio power amplifiers driving 4-ohm or 2-ohm speaker loads
• Vehicle infotainment systems utilizing I2C-bus control for diagnostics

Procurement Notes

Verify the specific ordering suffix N2C,118 against official documentation to confirm package type and marking details. Ensure compatibility with the required I2C address configuration via the ADSEL pin. Confirm that the HSOP36 package variant meets the thermal and mechanical requirements of the target application design.

Selection Notes

Select this component when a quad BTL amplifier with integrated I2C diagnostics is required. Consider the BCDMOS process for latch-up immunity and robust protection features. Evaluate the need for programmable clip and thermal thresholds versus fixed legacy mode operation based on system complexity.

Part Context

This part belongs to the TDA8595 family of I2C-bus controlled power amplifiers. It is designed for automotive applications where reliable operation under varying supply voltages and temperatures is critical. The TH package variant provides a heatsink small outline form factor suitable for efficient thermal management in compact vehicle installations.
