1.8 V Low-Voltage Narrowband FM-IF System - Sanyo
Description
Ordering number: EN 4077A
Monolithic Linear IC
LA8608V 1.
8 V Low-Voltage Narrowband FM-IF System
Overview
The LA8608V is a narrowband FM-IF system intended for communications equipment, operates at just 1.
8 V, and is contained in an ultrasmall package with a 0.
65 mm pitch.
In addition to the various functions needed for reception, the LA8608V also offers other functions such as noise detection and electric field intensity detection, and is optimum for compact designs, such as for cordless phones.
