20W+20W+20W AF Power Amplifier

Overview:

The STK400-030 is a 3-channel AF power amplifier IC supporting multichannel speakers. One package includes 20W×3ch for Lch, Rch and Cch. It is pin compatible with both 3-channel output devices (STK400-*00 series) and 2- channel output devices (STK401-*00 series). The output load impedance is 6/3Ω.

Features:

• New series combining 3-channel output devices (STK400-*00 series) and 2-channel output devices (STK401-*00 series) with the same pin compatibility. 
• Output load impedance is 6/3Ω. 
• Pin assignment is grouped into individual blocks of inputs, outputs and supply lines, minimizing the adverse effects of pattern layout on operating characteristics.
• Minimum number of external components required.

GENERAL DESCRIPTION:

The TDA8924 is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 × 120 W. The device comes in a HSOP24 power package with a small internal heatsink. Depending on supply voltage and load conditions a very small or even no external heatsink is required. The amplifier operates over a wide supply voltage range from ±12.
