GENERAL DESCRIPTION
The AD85631 is a precision instrumentation amplifier featuring
low noise, rail-to-rail output and a power-saving shutdown
mode. The AD8563 also features low offset voltage and drift
coupled with high common-mode rejection. In shutdown
mode, the total supply current is reduced to less than 4 μA.
The AD8563 is capable of operating from 2.7 V to 5.5 V.
The small package and low power consumption allow
maximum channel density and minimum board size for
space-critical equipment and portable systems.
The AD8563 is specified over the industrial temperature range
from −40°C to +125°C. The AD8563 is available in a Pb-free,
10-lead MSOP.
With a low offset voltage of 30 μV, an offset voltage drift of
0.5 μV/°C, and a voltage noise of only 1 μV p-p (0.01 Hz to
10 Hz), the AD8563 is ideal for applications where error sources
cannot be tolerated. Precision instrumentation, position and
pressure sensors, medical instrumentation, and strain gauge
amplifiers benefit from the low noise, low input bias current,
and high common-mode rejection. The small footprint and low
cost are ideal for high volume applications.
