TEA5570 Product details

Description

TEA5570 The TEA5570 is a monolithic integrated radio circuit for use in portable receivers and clock radios.The IC is also applicable to mains-fed AM and AM/FM receivers and car radio-receivers.Apart from the AM/FM switch function the IC incorporates for AM a double balanced mixer, 'one-pin' oscillator, i.f.amplifier with a.g.c.and detector, and a level detector for tuning indication.The FM circuitry comprises i.f.stages with a symmetrical limiter for a ratio detector.A level detector f

Features

Simple d. c. switching for AM to FM by only one d. c. contact to ground (no switch contacts in the i. f. channel, a. f. or level detector outputs).
AM and FM gain control.
Low current consumption (Itot = 6 mA).
Low voltage operation (VP = 2,7 to 9 V).
Ability to handle large AM signals; good i. f. suppression.
Applicable for inductive, capacitive and diode tuning.
Double smoothing of a. g. c. line.
Short-wave range up to 30 MHz.
