1001D 8pin IC


The 1001D is an infrared sensor analog front-end dedicated chip that integrates a two-stage operational amplifier, amplitude-amplifier comparator, and digital control unit to implement a single-chip processing solution for pyroelectric infrared sensor signals.
The 1001D integrates an LDO with 5mA output drive capability to power the pyroelectric sensor.
The 1001D integrates a light-controlled comparator to meet the application of light detection in intelligent lighting.
The 1001D's green ESOP8 package and minimal external components reduce PCB layout space. The 1001D can operate from -40 ° C to +85 ° C.
