GENERAL DESCRIPTION
The AD8226 is a low cost, wide supply range instrumentation
amplifier that requires only one external resistor to set any gain
between 1 and 1000.
The AD8226 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 AD8226 operates on supplies ranging from ±1.35 V
to ±18 V for dual supplies and 2.2 V to 36 V for single supply.
The robust AD8226 inputs are designed to connect to real-
world sensors. In addition to its wide operating range, the
AD8226 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 as well as maximum
input bias currents are specified to facilitate open wire detection.
The AD8226 is perfect for multichannel, space-constrained
industrial applications. Unlike other low cost, low power
instrumentation amplifiers, the AD8226 is designed with
a minimum gain of 1 and can easily handle ±10 V signals.
With its MSOP package and 125°C temperature rating, the
AD8226 thrives in tightly packed, zero airflow designs.
The AD8226 is available in 8-lead MSOP and SOIC packages,
and is fully specified for 40°C to +125°C operation.
For a device with a similar package and performance as the
AD8226 but with gain settable from 5 to 1000, consider using
