OPT4001 Digital Ambient Light Sensor

OPT4001 Description

OPT4001 SBOS993A * DECEMBER 2021 * REVISED DECEMBER 2022 OPT4001 High Speed, High Precision, Digital Ambient Light Sensor 1 .
The OPT4001 is a light-to-digital sensor (single chip lux meter) that measures the intensity of visible light.

OPT4001 Features

* High precision, high speed light-to-digital conversion over high speed I2C interface in two package variants
* Precision optical filtering to closely match human eye with excellent near infrared (IR) rejection
* Semi-logarithmic output with 9 binary logarithmic full-scale l

OPT4001 Applications

* External pin interrupt for hardware synchronized trigger and interrupts (only on SOT-5X3 package variant)
* Internal FIFO for output registers with I2C burst readout
* Low operating current: 30 μA with ultra-low power standby: 2 μA
* Operating temperature range:
