TDA1516BQ/N2,112

Overview

The TDA1516BQ/N2,112 is a class-B integrated power amplifier designed for car radio applications. It operates within a supply voltage range of 6.0 V to 18.0 V and delivers up to 24 W in bridge-tied load (BTL) mode or 2 x 12 W in stereo configuration. The device features a fixed gain of 20 dB per channel, low output offset voltage, and high ripple rejection. It includes mute/stand-by functionality with minimal current consumption and offers comprehensive protection against short circuits, thermal overload, reverse polarity, and load dumps.

Feature Summary

• Integrated class-B output amplifier configured for stereo or mono BTL operation
• Fixed internal gain with differential input stages for noise immunity
• Mute and stand-by switch capabilities with ultra-low standby current
• Robust protection mechanisms including thermal limiting, AC/DC short-circuit safety, and load dump tolerance

Applications

• Car radio power amplification
• Stereo audio systems requiring minimal external components
• Bridge-tied load (BTL) speaker driving configurations

Procurement Notes

Verify the specific ordering suffix N2,112 against manufacturer documentation to confirm packaging details and compliance status. Ensure compatibility with existing circuit designs regarding the 13-lead SIL plastic power package dimensions. Confirm that the fixed gain specification aligns with system requirements, as it differs from compatible models like the TDA1518Q.

Selection Notes

Select this component for automotive audio designs prioritizing high output power with reduced external part counts. The fixed 20 dB gain simplifies circuit design but requires verification against source impedance levels. Consider the 13-lead SIL package for through-hole mounting solutions where thermal dissipation needs are managed via PCB layout or heatsinking.

Part Context

Manufactured by Philips Semiconductors (now NXP), the TDA1516BQ belongs to a family of automotive audio power amplifiers. It is functionally similar to the TDA1518Q, though they differ in gain specifications. The device utilizes a 13-lead single-in-line plastic power package (SOT141-6) optimized for robust performance in vehicle electrical environments.

Replacement Considerations

The TDA1516BQ is noted as compatible with the TDA1518Q, except for differences in gain settings. Designers must account for the fixed 20 dB gain when substituting or upgrading within this product family.
