Miniature Dual 12-bit 1MSPS SAR ADC with PGA

MP

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 AK9240NK 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.

Key Features

  • Successive approximation type (SAR) ADC
  • Equipped with LED driver circuit and auto power control circuit

Applications

  •                                 Ideal for small optical encoders
