Intersil’s latest sensor sets new standard for handheld, PC, TV and industrial displays

Intersil Corporation has just introduced the ISL29035, a new and highly compact ambient and infrared sensor. According to Intersil it is the industry’s smallest 6-lead digital light sensor and looks to address the requirements for angular response and sensitivity to various light sources in handheld, PC, TV and industrial display applications.

The ISL29035 enables the automatic adjustment of display brightness based on the ambient light conditions to improve the user experience and extend battery life. The ISL29035 offers an angular response of a minimum of +/- 35% field of view at 50% light intensity. The wide dynamic range of 0.01 lux to 64,000 lux is intended to enhance the users’ visual experience while using minimal power. A lux range select feature allows users to program display brightness to suit various ambient light conditions, such as dark, normal and bright light.

The ambient light sensor’s advanced self-calibrated photodiode arrays emulate human eye response, providing excellent infrared (IR) light rejection. An on-chip charge-balancing 16-bit ADC rejects 50Hz and 60Hz flicker caused by artificial light sources.

In addition, the ISL29035 integrates a light-to-digital converter with an I2C (SMBus Compatible) interface to eliminate the need for a current amplifier, and ADC for interfacing to a system processor.
