Description

The AK9240NK is a 12-bit 2-channel 1MHz full differential input ADC with a band limiting filter and a programmable gain amplifier (PGA). It supports both current and voltage inputs.  In addition, the AK9240 even integrates an LED driver and an automatic power controlling circuits while it is housed in a small 3mm x 3mm QFN package. This device exerts a great effect on downsizing and boosting performance of optical encoders.

Applications

  •                                 Ideal for small optical encoders
