Chip Description
The EG4002 is a dedicated analog-digital hybrid chip designed for amplifying and processing signals from pyroelectric infrared sensors. It integrates an operational amplifier, dual-threshold voltage comparator, reference voltage source, delay timer, lockout timer, and state controller. It's specifically designed for applications such as anti-theft alarm systems, human body door control devices, and lighting control switches. The EG4002 operates with a supply voltage of +3V to +6V, uses a combined CMOS analog-digital integrated circuit process, and features an 8-pin package design. This reduces the number of external components and overall cost, saving PCB space.
