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) Supply Voltage (Pin3), VP 30V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
