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.
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 13 V D Sensitive IF amplifier for 10.7-MHz operating frequency D Logarithmic AM demodulator D FM demodulator D Monoflop output to wake up a microcontroller D High-performance operational amplifier to realize a data recovering filter D Non-inverting clamping comparator with amplitudedepending hyste.
