LM1818 Electronically Switched Audio Tape System

General Description

Features

Electronic record/play switching

The LM1818 is a linear integrated circuit containing all of the

active electronics necessary for building a tape recorder

deck (excluding the bias oscillator). The electronic functions

on the chip include: a microphone and playback preamplifi-

er, record and playback amplifiers, a meter driving circuit,

and an automatic input level control circuit. The IC features

complete internal electronic switching between the record

and playback modes of operation. The multipole switch

used in previous systems to switch between record and

playback modes is replaced by a single pole switch, thereby

allowing for more flexibility and reliability in the recorder de-

sign.*

85 dB power supply rejection

Motional peak level meter circuitry

Low noise preamplifier circuitry

3.5V to 18V supply operation

Provision for external low noise input transistor
