NTE1837 IC TV Tuner Controller

Formerly: ECG1837

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:
- Band Switch (Equivalent to the NTE1658: Refer to the Truth Table)
- Inverter
- Low-Pass Filter (Voltage Follower, Operational Amplifier)

Features:
- 2-Input, 5-Output Band Switch
- Band Switch (NTE1658) Available by Changing Over C Pin
- High Maximum Output Current, Low Saturation Voltage
- Meet CATV Tuner Requirements
- Frequency Synthesizer or Voltage Synthesizer Application depending on Inverter and Operational Amplifier Connections
