Sensing Products

Photodiode sensing

Highly integrated multichannel analog front ends (AFEs) for your photodiode designs

Integration

Small footprint, reliability and unique package options enable the most integrated devices on the market, supporting 1-256 channels.

Low power

Range of devices with ultra-low power, nap and power-down modes enable significant power savings.

Ease of use

Simplify your design with fewer external components, direct sensor access, products with integrated LED drivers and support resources.
