Monolithic Linear IC

LA4166M

Recording and Playback System

for Microcassette Players

Overview

The LA4166M is a recording and playback system IC that

incorporates an on-chip moter control governor, making it

ideal for use in microcassette and compact cassette record-

ers. The LA4166M features single-pin control for select-

ing recording or playback mode and a recording-mode in-

dicator LED driver. The LA4166M is pin-compatible with

the LA4165M. The LA4166M incorporates a preamplifier,

an automatic level control (ALC) circuit and a power am-

plifier.

The preamplifier functions as both recording microphone

amplifier and playback equalization amplifier. The ALC

circuit cuts high-level inputs and boosts low-level inputs

during recording. The power amplifier outputs 215mW (typ)

into a 4Ω speaker. The LA4166M operates from a 1.8 to

3.6V supply and is available in 24-pin MFPs.
