ISL29033IROZ-EVALZ

DATASHEET ISL29033 FN7656 Rev 5.00 September 28, 2016 Ultra-Low Lux, Low Power, Integrated Digital Ambient Light Sensor with Interrupt Function The ISL29033 is an integrated ambient and infrared light-to-digital converter with I2C (SMBus Compatible) interface. Its advanced, self-calibrated photodiode array emulates human eye response with excellent IR rejection. The on-chip 16-bit ADC is capable of rejecting 50Hz and 60Hz flicker caused by artificial light sources. The lux range select feature allows users to program the lux range for optimized counts/lux. Power consumption can be reduced to less than 0.3µA when powered down. Features The ISL29033 supports a software and hardware interrupt that remains asserted until the host clears it through the I2C interface. The function of ADC conversion continues without stopping after interrupt is asserted. • Program interrupt feature Designed to operate on supplies from 2.25V to 3.63V with an I2C supply from 1.7V to 3.63V, the ISL29033 is specified for operation across the -40°C to +85°C ambient temperature range. • 75μA maximum operating current - 0.3μA maximum shutdown current • Ambient light sensing • Simple output code directly proportional to lux • Variable conversion resolution up to 16 bits • Adjustable sensitivity up to 520 counts per lux • Measurement range: 0.0019 to 8,000lux with four selectable ranges • Light sensor close to human eye response - Excellent light sensor IR and UV rejection • 6 Ld 2.0mmx2.1mmx0.7mm ODFN package Applications Related Literature • Display and keypad dimming adjustment for: - Mobile devices: smart phone, PDA, GPS - Computing devices: notebook PC, webpad - Consumer devices: LCD-TV, digital picture frame, digital camera • Industrial and medical light sensing • For a full list of related documents, visit our web page - ISL29033 product page VDD 1 COMMAND REGISTER PHOTODIODE ARRAY INTEGRATION ADC LIGHT DATA DATA REGISTER PROCESS I2C/SMBus 5 SCL 6 SDA IREF INTERRUPT REGISTER fOSC 3 2 4 REXT GND INT FIGURE 1.
