GENERAL DESCRIPTION

The AD8227 is ideal for multichannel, space-constrained

applications. With its MSOP package and 125°C temperature

rating, the AD8227 thrives in tightly packed, zero airflow designs.

The AD8227 is a low cost, wide supply range instrumentation

amplifier that requires only one external resistor to set any gain

between 5 and 1000.

The AD8227 is available in 8-pin MSOP and SOIC packages.

It is fully specified for −40°C to +125°C operation.

The AD8227 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 AD8227

operates on supplies ranging from 1.5 ꢀ to 18 ꢀ ꢁ2.2 ꢀ to

36 ꢀ single supply).

For a similar instrumentation amplifier with a gain range of 1 to

1000, see the AD8226.

The robust AD8227 inputs are designed to connect to real-

world sensors. In addition to its wide operating range, the

AD8227 can handle voltages beyond the rails. For example,

with a 5 ꢀ supply, the part is guaranteed to withstand 35 ꢀ

at the input with no damage. Minimum as well as maximum

input bias currents are specified to facilitate open wire detection.
