EG4002 Pyroelectric infrared induction  chip

 8-pin infrared pyroelectric special chip, simple peripheral circuit, low cost
Low static power consumption, less than 45ua for 3V working power supply and less than 75ua for 5V working power supply, very suitable for battery power supply system application
High input impedance operational amplifier, which can be matched with a variety of sensors for signal and processing
• bidirectional amplitude discriminator, which can effectively suppress interference
• built in reference voltage for internal comparator and op amp
The delay time timer and lock time timer are set in the system. The delay time can be set by changing the oscillator frequency.
There are few peripheral components, so only the gain of the first stage operational amplifier and the RC device of the oscillator can work reliably.
Working power supply + 3V to + 6V
- package form: sop8 and DIP8
