Datasheet Summary
Low-Current Superhet Remote Control Receiver
Description
The U4311B-FS is a monolithic integrated circuit in bipolar technology for low-current UHF remote control super-heterodyne receivers in amplitude- or frequencymodulated 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.
Features
D Usable for amplitude- and frequency-modulated transmission systems D Extremely low quiescent current (approximately 1 mA in standby mode due to wake-up concept) D Wide power supply voltage range 3 to...
