TDA8922BTH/N2,118

Overview

The TDA8922BTH/N2,118 is a high-efficiency Class-D audio power amplifier manufactured by NXP USA Inc. It operates within a supply voltage range of ±12.5 V to ±30 V and features a typical total quiescent current of 65 mA. In stereo single-ended configuration with a ±26 V supply, it delivers up to 50 W into a 6 Ω load at 10% THD. For mono bridge-tied load (BTL) applications, it provides up to 88 W into an 8 Ω load under the same conditions. The device utilizes a fixed gain of 30 dB in SE mode and 36 dB in BTL mode.

Feature Summary

• Zero dead time switching for reduced power loss
• Smooth start-up mechanism preventing pop-noise from DC offset
• Advanced current protection with output current limiting
• Full short-circuit proof capability across load and supply lines

Applications

• Television sets
• Home-sound systems
• Multimedia systems
• Mains-fed audio systems
• Car audio boosters

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as the HSOP24 form factor requires careful handling. Ensure compliance with RoHS3 specifications and check for any specific material declarations required for your manufacturing process. Validate that the ordering suffix matches your design requirements exactly.

Selection Notes

Select this component for designs requiring high efficiency and low dissipation in stereo or mono configurations. Consider the thermal resistance characteristics when designing heatsinking solutions, as junction temperature limits must be respected. Evaluate the need for external clock synchronization if multiple amplifiers are used in close proximity to avoid interference issues.

Part Context

This part belongs to the TDA8922B family of Class-D audio amplifiers. It is available in the HSOP24 plastic heatsink small outline package. The device integrates high-power D-MOS switches, drivers, and control logic on a single chip. It supports both stereo single-ended and mono bridge-tied load operations, offering flexibility in system architecture.
