DESCRIPTION: The EUA5202 is a stereo audio power amplifier that  delivering 2W of continuous RMS power per channel   into 3-Ω loads. When driving 1W into 8-Ω speakers, the   EUA5202 has less than 0.04% THD+N across its   specified frequency range. Included within this device is  integrated de-pop circuitry that virtually eliminates   transients that cause noise in the speakers.   Amplifier gain is externally configured by means of two   resistors per input channel and does not require external   compensation for settings of 2 to 20 in BTL mode (1 to   10 in SE mode). An internal input MUX allows two sets   of stereo inputs to the amplifier. In notebook   applications, where internal speakers are driven as BTL   and the line (often headphone drive) outputs are required   to be SE, the EUA5202 automatically switches into SE   mode when the SE/BTL inputs is activated. Consume   only 7mA of supply current ...

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. Circuit Diagram: 20W+20W+20W AF Power Amplifier

Description STA516B is a monolithic quad half-bridge stage in multipower BCD technology. The device can be used as dual bridge or reconfigured, by connecting pin CONFIG to pins VDD, as a single  bridge with double-current capability or as a half bridge (binary mode) with half current capability. The device is designed, particularly, to be the  output stage of a stereo all digital high efficiency  amplifier. It is capable of delivering 200 W + 200 W into 6  loads with THD = 10% at VCC = 51 V or, in single BTL configuration, 400 W  into a 3 load with THD = 10% at VCC = 52 V. The input pins have a threshold proportional to the voltage on pin VL. The STA516B is aimed at audio amplifiers in hi-fi applications, such as home theatre systems, active speakers and docking stations. It comes in a 36 pin PowerSO package with exposed pad up (EPU).
