NTE7147
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:
D Pre–Amplifier with Differential High CMRR Current Mode Inputs
D Low Offsets
D High Linear Sawtooth Signal Amplification
D High Efficient DC–Coupled Vertical Output Bridge Circuit
D Powerless Vertical Shift
D High Deflection Frequency up to 160Hz
D Power Supply and Flyback Supply Voltage Independent Adjustable to Optimize Power
Consumption and Flyback Time
D Excellent Transition Behaviour Duriing Flyback
D Guard Circuit for Screen Protection
Absolute Maximum Ratings: (Voltage referenced to Pin5 (GND) unless otherwise specified)
