The AD8226ARZ is a wide supply range, rail-to-rail output Instrumentation Amplifier that requires only one external resistor to set any gain between 1 and 1000. This is designed to work with a variety of signal voltages. A wide input range and rail-to-rail output allow the signal to make full use of the supply rails. Because the input range also includes the ability to go below the negative supply, small signals near ground can be amplified without requiring dual supplies. The robust inputs are designed to connect to real world sensors. In addition to its wide operating range, this can handle voltages beyond the rails. For example, with a ±5V supply, the part is guaranteed to withstand ±35V at the input with no damage. Minimum as well as maximum input bias currents are specified to facilitate open wire detection. This is perfect for multichannel, space-constrained industrial applications.
