High Voltage Input Amplifier Circuit for Hi-Fi Power Amplifier
s Overview
The AN7062N is a high voltage integrated circuit de-
signed for pre-driver of 60W-class Hi-Fi audio amp.
Stereo operation is enabled due to two amplifiers built-in.
s Features
• High voltage
• Low noise : V_ni = 2.5µV (typ.)
• Low distortion : THD = 0.003% (typ.)
• Good channel separation
• Wide operating supply voltage range
