AS7150 Optical force sensing analog front

end

General description

The AS7150 is a low noise, high dynamic range proximity detection analog front end that has

been optimized for optical force sensing application for consumer market.

The device consists of two low-noise ADC channels capable of simultaneous acquisition of two

photodiodes. The integrated LED driver and high integration factor with the small

1.67 mm x 1.67 mm WLCSP package is ideally suited for space constraint force and proximity

applications where the optical front end needs to be decoupled from the analog front end.

The proximity function synchronizes IR emission and detection to sense nearby objects. The

architecture of the engine features low noise, high dynamic range, ambient light subtraction,

FIFO and interrupt-driven I²C communication.

Sensitivity, power consumption, and noise can be optimized with adjustable LED timing and

power. The proximity engine recognizes detect/release events and produces a configurable

interrupt whenever the proximity result crosses the upper or lower threshold settings.
