NTE1580 Datasheet | NTE Electronics

Description : The NTE1580 is an IF amplifier in a 14- Lead DIP type package with a symmetrical FM demodulator and an AF amplifier with adjustable output voltage. The AF amplifier is also provided with an output for volume control and an input for VCR operation. The input and output of the NTE1580 are especially designed for LC- circuits, but the input can also be used with a ceramic filter.
