Dual 12bit 1MSPS SAR ADC

  • Inquiry


The AK9235NK is a 1.03 MSPS 12-bit successive approximation A/D converter.
It supports a wide range of power supply voltage realizing to compose a general purpose system while reducing the cost.
The AK9235NK has small input capacitance. Therefore electric characteristics of the system can be achieved easily.
Moreover, low power consumption is accomplished, enabling to reduce the system power dissipation.
The AK9235NK is available in a small package, saving space on the printing board.
