1000. Furthermore, the AD620 features 8-lead SOIC and DIP
packaging that is smaller than discrete designs, and offers lower
power (only 1.3 mA max supply current), making it a good fit
for battery powered, portable (or remote) applications.
The AD620, with its high accuracy of 40 ppm maximum
nonlinearity, low offset voltage of 50
μ
V max and offset drift of
0.6
μ
V/
°
C max, is ideal for use in precision data acquisition
systems, such as weigh scales and transducer interfaces. Fur-
thermore, the low noise, low input bias current, and low power
of the AD620 make it well suited for medical applications such
as ECG and noninvasive blood pressure monitors.
The low input bias current of 1.0 nA max is made possible with
the use of Super
β
eta processing in the input stage. The AD620
works well as a preamplifier due to its low input voltage noise of
9 nV/
Hz
at 1 kHz, 0.28
μ
V p-p in the 0.1 Hz to 10 Hz band,
0.1 pA/
Hz
input current noise. Also, the AD620 is well suited
for multiplexed applications with its settling time of 15
μ
s to
0.01% and its cost is low enough to enable designs with one in-
amp per channel.
