E931.95中文资料PIR Controller Integrated Circuit数据手册Elmos规格书

描述 Description

The E931.95 integrated circuit combines all required functions for a single chip Passive Infra Red (PIR) motion detector. Motion detection is signaled through a push-pull output. A daylight sensor input simplifies sensor light applications.
A LED output indicates whenever the PIR Signal is above the selected threshold. The E931.95 interfaces directly with up to two conventional PIR sensors via a high impedance differential input. The PIR signal is converted to a 16 bit digital value on chip.
The parameters for sensitivity and timing are set by connecting the corresponding inputs to DC voltages. The voltage levels on the inputs are converted to digital values with 7 bit resolution. All signal processing is performed digitally. Drift and aging are not possible. The Integrated circuit does not require any electrolytic capacitors for its basic application. The E931.95 is available in TSSOP14 and SOIC14 packages.
