The TAS5142DKD from Texas Instruments is a third-generation, high-performance, integrated stereo digital amplifier power stage designed for audio applications. It is capable of driving a 4-ohm bridge-tied load (BTL) at up to 100W per channel, with a low integrated noise output and low THD+N performance.
Key electrical specifications include an output power of 100W into 4 ohms (BTL), 80W into 6 ohms (BTL), and 65W into 8 ohms (BTL), all at 10% THD+N. It boasts a signal-to-noise ratio (SNR) greater than 100 dB (A-weighted) and total harmonic distortion plus noise (THD+N) of less than 0.1% at 1W. The power stage efficiency is greater than 90%.
This device requires supply voltages of 12V for GVDD and VDD, and 32V for PVDD. It features integrated self-protection circuits including undervoltage, overtemperature, overload, and short circuit protection. The TAS5142DKD is available in a thermally enhanced DKD package, which is a 36-pin PSOP3.
Applications for the TAS5142DKD include mini/micro audio systems, DVD receivers, and home theater systems. It is designed to work with a TI chipset, requiring only a simple passive LC demodulation filter for high-fidelity, high-efficiency audio amplification.
The TAS5142DKD is available in a 36-pin PSOP3 DKD package.
The amplifier supports BTL (2×100W into 4Ω), SE (4×30W into 4Ω), and PBTL (1×200W into 2Ω) configurations at 10% THD+N.
The SNR is greater than 100dB (A-weighted).
THD+N is less than 0.1% at 1W.
Efficiency exceeds 90%.
The device requires 12V for GVDD and VDD, and 32V for PVDD.
