AUDIO POWER AMPLIFIER IC

Overview
The STK404-230-E is a hybrid IC designed to be used in 100W (1-channel) class AB AUDIO POWER AMPLIFIERs.

Features
• 1-channel AUDIO POWER AMPLIFIER
• Built-in standby circuit
• Overcurrent protection
• Output DC offset protection
• Shutdown circuit when latch-up occurs
• Error signal output (open collector)

ApplICations
• AUDIO POWER AMPLIFIERs.

Overview
The LV4920H is a 2-channel BTL full-bridge driver for digital POWER AMPLIFIERs. It requires a PWM modulator IC in the previous stage. This IC is a POWER cell that takes in PWM signals as an input and is used to form a digital AMPLIFIER system for TVs, amusement equipment, and other such systems.

Features
• BTL output, class D AMPLIFIER system
• High-effICiency class D AMPLIFIER
• Muting function reduces impulse noise at POWER on/off
• Full complement of built-in protection circuits: overcurrent protection, thermal protection, and low POWER supply voltage protection circuits
• Built-in bootstrap diodes

ApplICation
• TV sets (PDP/LCD)
• Amusement equipment (pinball or pinball-slot-machines)
• Home AUDIO equipment (mini-/mICro-AUDIO systems)
• Home theater equipment
