Min Voltage (typical range): 2.4 V
Length: 2 mm
Description
The NOA1312 high-precision ambient light sensor (ALS) is designed for very high accuracy (better than ±5% tolerance) handheld applications. The device integrates a 16-bit ADC, a 2-wire I2C digital interface with three pin-selectable I2C slave addresses, internal clock oscillator, EEPROM and a power down mode.
Key Features
- Senses Ambient Light and Provides an Output Count Proportional to the Ambient Light Intensity
- Human Eye Spectral Response using Photopic Optical Filter
- Dynamic Dark Current Compensation
- Very High Accuracy (better than ±5% tolerance)
- Ev Sensitivity of 5.2 Counts/lux
- Less than 240 mA Active Power Consumption in Normal Operation
- Ultra-low Quiescent Power Dissipation, less than 100 nA in Power Down Mode (below 50°C)
- Interrupt Signal Notifies Host of Significant Intensity Changes
- Internal EEPROM Stores Values to Minimize Programming Time
- Register Values Preserved during Power-down Mode
