NTE1837 Integrated Circuit TV Tuner Controller
Description: The NTE1837 is a tuner controller integrated circuit in a 16–Lead DIP type package containing functions such as band switch, inverter, and low–pass filter. This device can be used as a frequency synthesizer or a
voltage synthesizer, depending on the external application circuit. Functions: D Band Switch (Equivalent to the NTE1658: Refer to the Truth Table) D Inverter D Low–Pass Filter (
Voltage Follower, Operational Amplifier) Features: D 2–Input, 5–Output Band Switch D Band Switch (NTE1658) Available by Changing Over C Pin D High Maximum Output Current, Low Saturation
Voltage D Meet CATV Tuner Requirements D Frequency Synthesizer or
Voltage Synthesizer Application depending on Inverter and Operational Amplifier Connections Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Band Switch VCC1 Maximum Supply
