TEA5570 Overview
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.
Key Features
- 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
- Lumped or distributed i.f. selectivity with coil and/or ceramic filters
- AM and a.g.c. output voltage control
- Distribution of PCB wiring provides good frequency stability
