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).

Description

The TDA1400 is a one-channel, Amplifier Driver that uses Tripath’s proprietary Digital Power Processing  (DPPTM) technology. The TDA1400 offers higher integration over previous Tripath amplifiers driver  chipsets while providing exceptional audio performance for real world applications. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers. The TDA1400 is typically configured as a single supply, bridged output. This makes the power supply requirements simpler and maximizes the output power for a given voltage rail. Additionally, the TDA1400 can be configured as a split supply, bridged amplifier, with the addition of some external components. The TDA1400 is capable of full range operation but the target application is subwoofers due to the high output power capability and single channel operation.
