The TDA8954J is a stereo or mono high-efficiency Class D audio power amplifier from NXP Semiconductors, designed for low power dissipation. It can deliver up to 2 x 210 W into a 4 Ω load in a stereo Single-Ended (SE) application, or 1 x 420 W into an 8 Ω load in a mono Bridge-Tied Load (BTL) application.
This amplifier combines the benefits of Class D efficiency, reaching 93% into a 4 Ω load, with audiophile sound quality comparable to Class AB amplification. It operates over a wide supply voltage range from ±12.5 V to ±42.5 V and features low quiescent current consumption. The TDA8954J is supplied with two diagnostic pins for monitoring the status of Thermal Fold Back (TFB) and Over Current Protection (OCP) circuits.
Key specifications include a gain of 36 dB, a Common Mode Rejection Ratio (CMRR) of at least 75 dB, and a THD plus Noise of 0.03%. The amplifier is suitable for differential input signals and provides differential or single output signals. It is available in a DBS23P package and is designed for through-hole mounting.
The operating temperature range for the TDA8954J is from -40 °C to +85 °C. It is RoHS3 compliant, has an MSL rating of 1, and is REACH unaffected. This component is ideal for applications requiring high-quality audio amplification with excellent efficiency.
In stereo single-ended mode at 4Ω, it delivers 210W per channel. In mono bridge-tied load mode at 8Ω, it delivers 420W.
The efficiency is 93% at 4Ω load.
The dual supply voltage range is ±12.5V to ±42.5V.
The operating temperature range is -40°C to +85°C.
It is available in a DBS23P through-hole package.
THD+N is 0.03% at nominal conditions.
The fixed gain is 36dB.
