Monolithic Linear IC
LA8670M
Double-Conversion Narrow-Band
FM IF System
Overview
The LA8670M is a narrow band FM IF system for use in
communication equipment. In addition to the functions
required for FM reception, the LA8670M provides a rich
set of additional functions including noise detection and
field strength detection, and is thus optimal for cordless
telephones.
Functions
• First mixer, first local oscillator, first local oscillator
buffer output, second mixer, second local oscillator
• IF amplifier, limiter, quadrature detector
• Signal meter
• Noise detector, noise amplifier, noise wave detector,
Schmitt trigger
Features
• Low voltage operation: VCC OP = 1.8 to 6 V
• Signal meter linear over a wide range (70 dB typical)
• High sensitivity, high intercept point
