  • Description

    The AD8227ARMZ is a low cost, wide supply range instrumentation amplifier designed for use with a variety of signal voltages. It requires only one external resistor to set any gain between 5 and 1000. Its wide input range and rail-to-rail output allow the signal to make full use of the supply rails and can go below the negative supply, which is useful for amplifying small signals near ground without requiring dual supplies.

    This model can operate on supplies ranging from ±1.5 V to ±18 V (2.2 V to 36 V single supply) and its inputs are designed to connect to real-world sensors. The device has a robust input range and can handle voltages beyond the rails. With a ±5 V supply, the part is guaranteed to withstand ±35 V at the input with no damage. The AD8227 allows for open wire detection as minimum and maximum input bias currents are specified.

    With its MSOP package and 125°C temperature rating, the AD8227ARMZ is ideal for multichannel, space-constrained applications and can thrive in tightly packed, zero airflow designs.
