Monolithic IC LMF501

Outline

This is a monolithic IC designed for use as a single-chip AM radio. It can be used to configure an AM radio

with few external components.

It is ideal for use in watch radios, lighter-radios and other applications intended to operate on low voltage and

current.

Features

1. Operation at low voltages possible

2. Operates with low current consumption

3. Compact, lightweight

4. Broad AGC range

VCC : 1.1V
