LM1818 Datasheet Electronically Switched Audio Tape System

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM1818 Electronically Switched Audio Tape System April 1987 LM1818 Electronically Switched Audio Tape.

General Description

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 preamplifier record and playback amplifiers a meter driving circuit and an automatic input level control circuit The IC

Key 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 design Monaural operation Figure 9 Features Y Y Y Y Y Y Electronic record play switching 85 dB power supply rejection Motional peak level meter circuitry Low noise preamplifier circuitry 3 5V to 18V supply operat.
