TDA2616Q/N1,112

Overview

The TDA2616Q/N1,112 is a dual power amplifier designed for hi-fi audio applications. It delivers 12 W output power per channel into an 8 Ω load with a ±16 V supply and 0.5% THD. The device operates within a supply voltage range of ±7.5 V to ±21 V. It features a fixed internal voltage gain of 30 dB and includes input mute functionality to suppress switch-on/off clicks. The component utilizes a 9-lead SIL-bent-to-DIL plastic package (SOT157) and incorporates short-circuit and thermal protection.

Feature Summary

• Integrated input mute circuit eliminates switch-on and switch-off noise
• Fixed internal voltage gain ensures excellent balance between amplifiers
• Built-in thermal and short-circuit protection mechanisms
• Compliant with IEC 268 and DIN 45500 hi-fi standards

Applications

• Stereo radio systems
• Stereo television sets
• Mains-fed audio equipment
• Hi-fi audio power amplification

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure compatibility with required packaging or environmental specifications. Confirm that the SOT157 package variant matches the intended PCB footprint and mounting requirements for the application design.

Selection Notes

Select this component for stereo audio designs requiring high fidelity and minimal external components. Ensure the power supply can provide symmetrical voltages up to ±21 V. Consider the thermal resistance requirements for heatsinking if operating near maximum power dissipation limits in enclosed environments.
