描述 Description

The U4311B-FS is a monolithic integrated circuit in bipolar technology for low-current UHF remote control

super-heterodyne receivers in amplitude- or frequency modulated mode. Typical applications are keyless car

lock-, alarm- or tele-control remote indication systems. Especially for automotive applications, it supports a

superhet design with about 1 mA total current consumption as required by the car manufacturers.

特性 Features

Usable for amplitude- and frequency-modulated transmission systems

Extremely low quiescent current (approximately 1 mA in standby mode due to wake-up concept)

Wide power supply voltage range 3 to 13 V

Sensitive IF amplifier for 10.7-MHz operating frequency

Logarithmic AM demodulator

FM demodulator

Monoflop output to wake up a microcontroller

High-performance operational amplifier to realize a data recovering filter

Non-inverting clamping comparator with amplitude depending hysteresis for data regeneration
