Integrated Circuit
Full Bridge Current Driven Vertical Deflection Booster
Description:
The NTE7147 is a power amplifier in a 9–Lead SIP type package designed for use in 90 degree color
vertical deflection systems for frame frequencies of 50Hz to 160Hz. This device provides a high
CMRR current driven differential input. Due to the bridge configuration of the two output stages, DC–
coupling of the deflection coil is achieved.
Features:
Pre–Amplifier with Differential High CMRR Current Mode Inputs
Low Offsets
High Linear Sawtooth Signal Amplification
High Efficient DC–Coupled Vertical Output Bridge Circuit
Powerless Vertical Shift
High Deflection Frequency up to 160Hz
Power Supply and Flyback Supply Voltage Independent Adjustable to Optimize Power
Consumption and Flyback Time
Excellent Transition Behaviour Duriing Flyback
Guard Circuit for Screen Protection
