Product Overview
The VEML7700 is a high-accuracy, 16-bit digital ambient light sensor featuring an I2C interface. Housed in a miniature 6.8 mm x 2.35 mm x 3.0 mm package, it integrates a highly sensitive photodiode, a low-noise amplifier, and a 16-bit A/D converter. Its FiltronTM technology closely mimics human eye response, while O-TrimTM technology ensures ALS output tolerance of 10%. With a dynamic range from 0 lx to 120 klx and a resolution down to 0.0036 lx/ct, it supports low transmittance lens designs and offers 100 Hz and 120 Hz flicker noise rejection. Applications include backlight dimming for displays (TVs, smartphones, PDAs, GPS), industrial lighting control, and optical switching for consumer, computing, and industrial devices.
