Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADPD188BI-ACEZRL is a complete smoke photometric detection system with dual wavelength optics. The module integrates a high-efficiency photometric front-end, two light-emitting diodes (LEDs) and two photodiodes (PDs). Light travels directly from the LEDs to the photodiodes without first entering the smoke detection chamber. The ASIC front end includes a control block, a 14-bit analogue-to-digital converter (ADC) and three flexible, independently configurable LED drivers. The control circuitry includes flexible LED signalling and synchronised detection.

Features

● 3.8 mm × 5.0 mm × 0.9 mm module with integrated optics assembly

● 1 blue LED, 1 IR LED and 2 photodiodes

● 2 external inputs for other sensors (e.g. carbon monoxide (CO) and temperature)

● (CO) and temperature) 

● Three 370 mA LED drivers

● 20-bit burst accumulator, 20 bits per sample cycle

● On-board sample-to-sample accumulator with up to 27 bits per data reading

● SNR optimised for signal-limited conditions

● I2C or SPI communication

Applications

● Smoke detection

• 1.Is the inventory and price seen on the platform accurate?
