U4311B-FS
Overview
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.
- 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 amplitudedepending hysteresis for data regeneration
