GENERAL DESCRIPTION

The AD8426 is a dual-channel, low cost, wide supply range instrumentation amplifier that requires only one external resistor to set any gain from 1 to 1000.

The AD8426 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 can also go below the negative supply, small signals near ground can be amplified without requiring dual supplies. The AD8426 operates on supplies ranging from ±1.35 V to ±18 V for dual supplies and 2.2 V to 36 V for a single supply.

The robust AD8426 inputs are designed to connect to real world sensors. In addition to its wide operating range, the AD8426 can handle voltages beyond the rails. For example, with a ±5 V supply, the part is guaranteed to withstand ±35 V at the input with no damage. Minimum and maximum input bias currents are specified to facilitate open-wire detection.
