NTE7135
Integrated Circuit
Vertical Deflection Power Amplifier for Monitors
Description:
The NTE7135 is a vertical power amplifier for differential input signals in a 9–Lead SIP type package
suitable for color monitor/TV systems with deflection frequencies up to 140Hz.
Features:
Vertical Pre–Amplifier with Differential Inputs
Powerless Vertical Shift
Flyback Voltage Generation Suitable for Two Operating Modes (Doubling the Supply Voltage
or External Supply for the Short Flyback Time, this Achieves a Minimum of Power Dissipation)
Vertical Output Stage with Thermal and SOAR Protection
High Deflection Frequency up to 140Hz
High Linear Sawtooth Signal Amplification
Possibility of Guarding the Deflection
Voltage Stabilizer
Absolute Maximum Ratings:
