Introduction

LW310 is a low-cost, highly integrated RF IC designed for AM communication systems. It includes an RF oscillator, a microphone amplifier and a speaker driver. It is particularly suitable for walke-talkie application in the frequency band from 27MHz to 49MHz. By changing a few external components, energy saving LW310 can also support other applications such as interactive radio-controlled toy and short distance voice/data communicator.
