Product specification

TDA1574

GENERAL DESCRIPTION

The TDA1574 is a monolithic integrated FM tuner circuit designed for use in the r.f./i.f. section of car radios and

home-receivers. The circuit comprises a mixer, oscillator and a linear i.f. amplifier for signal processing, plus the following

additional features.

Features

• Keyed automatic gain control (a.g.c.)

• Regulated reference voltage

• Buffered oscillator output

• Electronic standby switch

• Internal buffered mixer driving.
