NTE805

Integrated Circuit

IF Gain Block for FM Receiver

Description:

The NTE805 provides function of an IF gain block and is designed for use in communications and FM

receivers. The device consists of a three−stage limiting amplifier operating from a regulated power

supply, and 330

Ω input and output terminations with 7.0pF of shunt capacitance required for 10.7MHz

ceramic filters. The device also offers a 7.7 voltage regulated supply for external use from pin 6.

Features:

D Gain at 10.7MHz: 35dB Typ.

D Operating Voltage Range: 10V to 20V

D Excellent Temperature Stability

D Power Supply Rejection Ratio: 40dB Typ.

Absolute Maximum Ratings:

20V
