The Optoelectronics group of Vishay Intertechnology unveils a new high-accuracy digital ambient light sensor for consumer and industrial applications. The Vishay Semiconductors VEML6030 claims to combine a highly sensitive photo-diode, low-noise amplifier, and 16-bit ADC in a miniature, transparent surface-mount package measuring only 2 mm by 2 mm by 0.85 mm.
- The sensor adopts Filtron technology and features an interrupt function while supporting an I²C bus interface for simple operation.
- Operating over a temperature range of -25 °C to +85 °C, the devices are touted to provide display and keypad dimming adjustment and optical switching for mobile devices such as smartphones and GPS units; notebooks and PC computers; LCD TVs, digital picture frames and digital cameras; and industrial and medical light sensing.
- As part of smart home lighting control systems, the VEML6030 provides accurate and current analysis of ambient lighting to give precise control even during unexpected situations, such as fast-moving storms. The device detects fading natural light and can detect the sun rising in the morning to control light levels.
- Filtron technology enables ambient light spectral sensitivity close to that of the human eye, while the sensor’s adoption of O-Trim technology provides output tolerance of ≤ 10 % offering detection from 0 lx to 167 klx and resolution down to 0.005 lx/ct, allowing for operation in applications with low-transmittance (dark) lens designs. The VEML6030 provides 100 Hz and 120 Hz flicker noise rejection and excellent temperature compensation stability. The device features low power consumption down to just 2 μA in operating mode and 0.5 μA in shutdown mode.
The VEML6030’s supply voltage range is from 2.5 V to 3.6 V, while its I²C bus voltage range is from 1.7 V to 3.6 V. Offered in a lead (Pb)-free, 6-pin package, the device is RoHS-compliant, halogen-free, and Vishay Green.
Samples of the new ambient light sensor are exclusively obtainable. Production quantities will be available in Q2 2016, with lead times of 12 weeks for large orders.
