AN5768
TILT correction IC
■ Overview
The AN5768 is a rotation correction (TILT) IC for
CRT monitor incorporating a driving transistor. It enables
±250 mA (max.) DC current flow by connecting a coil
between the output pins which operate with a reverse
phase each other.
■ Features
• DC control input: 0 V to 5 V
• Output dynamic range: 1.2 V to 3.8 V
• Maximum output current: ±250 mA
■ Applications
• CRT monitors
