Monolithic Linear ICs

Single-Chip Tuner ICs

for Use in Radio Cassette Recorder

Overview

The LA1823 and the LA1823M are single-chip tuner ICs that incorporate FM/AM and MPX circuits and support

electronic tuning. The built-in MPX-VCO allows these ICs to be adjustment-free and to require no external components.

Features

• AM, FM frontend/IF and MPX integrated in a single-chip.

• Built-in MPX VCO circuit

• Electronic tuning (AM oscillator output, AM/FM IF output)

• Adjustment-free FM detection (uses a ceramic discriminator)

• Packages : DIP24S (300mil) [LA1823]

MFP24S (300mil) [LA1823M]

Functions

AM : RF amplifier, mixer, oscillator, oscillator buffer, IF amplifier, detector, AGC, IF count buffer output.

FM-RF : RF amplifier, mixer, and oscillator.

FM-IF : IF amplifier, quadrature detector, S-meter, and IF counter buffer output.

MPX : PLL stereo decoder, stereo indicator, forced monaural, VCO on chip, Audio mute.
