Integrated Circuit
Low Level Video Detector
Description:
The NTE747 is a low level video detector in an 8–Lead DIP type package featuring very linear video
characteristics and bandwidth. Designed for color and monochrome television receivers, replacing
the third IF, detector, video buffer, and the AFC buffer.
Features:
D Conversion Gain: 34dB Typ
D Video Frequency Response @ 6MHz < 1dB
D Input of 36mV Produces 3V_P–P Output
D High Video Output: 7.7V_P–P
D Fully Balanced Detector
D High Rejection of IF Carrier
D Low Radiation of Spurious Frequencies
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
