OPT4041 High Speed, Dual-Channel, High Precision, Digital Ambient Light Sensor

1 Features

High precision, high speed light-to-digital conversion over high speed I²C interface
Visible channel:
- Precision optical filtering to closely match human eye with excellent near infrared (IR) rejection
- 28 bits of effective dynamic range: 585μlux to 157klux
Wide band channel:
- Responsive to a wide range of wavelengths, including NIR
- 26 bits of effective dynamic range: 192.3pW/cm² to 12.91mW/cm²
Semi-logarithmic output:
- 9 (visible channel) and 7 (WB channel) binary logarithmic full-scale light ranges
- Highly linear response within each range
Built-in automatic full-scale light range selection logic that switches measurement range based on input light condition for best possible resolution at all times
12 configurable conversion times:
- 600μs to 800ms per channel for high-speed and high-precision applications
External pin interrupt for hardware synchronized trigger and interrupts
Internal FIFO on output registers with I²C burst readout
Low operating current: 30μA
with ultra-low power standby: 2μA
Operating temperature range: –40°C to +85°C
Wide power-supply range: 1.6V to 3.6V
5.5V Tolerant I/O pins
Selectable I²C address
Small-form factor:
- 2.1mm × 1.9mm × 0.6mm SOT-5X3 package
