Two-Channel 20 W BTL Audio Power Amplifier

Overview:
The LA4628 is a 2-channel general-purpose BTL audio power amplifier provided in a miniature package. It was designed for the best possible audio quality and features an extended low band roll-off frequency provided by a newly-developed NF circuit that does not require an external capacitor. Furthermore, crosstalk, which can cause muddiness in the audio output, has been significantly reduced by both circuit and wiring pattern improvements. Thus this amplifier can provide powerful lows an clear highs. Note that this device is pin compatible with the 13.5 W × 2-channel LA4625, and allows end products differentiated by their power rating to share the same printed circuit board.
Features: Total output: 20 W + 20 W (at VCC = 13.5 V, RL = 4 Ω,THD = 10%)High-fidelity design (fL < 10 Hz, fH = 130 kHz)Extremely low impulse noise levelsAn arbitrary amplifier startup time can be set up with external components.Full complement of built-in protection circuits (includes circuits that prote…

2 x 200W or 400W BTL 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).
