产品概览
The AD8226ARZ is a low-cost, wide-supply-range instrumentation amplifier from Analog Devices with rail-to-rail output. Operating from a single 2.2V to 36V supply (or dual ±1.35V to ±18V), it sets gain from 1 to 1000 with one external resistor. The input range extends below the negative supply, and inputs tolerate ±35V beyond the rails with ±5V supplies. With 90dB CMRR (B grade), 1.5MHz bandwidth, and 350µA supply current, it is ideal for industrial and portable multi-channel applications.
