Question Can I replace AD620 or AD8221 directly with AD8422 in my circuit? Answer AD8422 is only available in the High-Performance Pinout which was introduced by
the AD8221, so a board layout change…
Q
What are some common pitfalls to avoid while designing with AD8422?
A
AD8422 is a high performance precision instrumentation amplifier. In order to achieve the optimum performance, it must be…
Question Is there an evaluation board and a spice model for the AD8422 to help me
accelerate the design and verification process? Answer Yes. The AD8422 is compatible with the EVAL-INAMP-82RZ (SOIC version…
Question ADI already has many instrumentation amplifiers that are highly respected. What
differentiates the AD8422 from previous products? Answer AD620 set an industry standard for instrumentation amplifier…
Question You mentioned rail-to-rail output. Is the AD8422 intended for single-supply
applications? Answer The AD8422 works on a wide range of supplies from +3.6V single supply to ±18V
dual-supply,…
Question Looking through the output range specification, I noticed a large number for
2kΩ load and ±15V supply. Why is that? Answer The built in short-circuit current-limit for the AD8422 output varies…
Question Are there any performance differences between the AD8422 SOIC and MSOP package
options? Answer There are some slight variations between specifications of the SOIC and MSOP.
In general, the…
Question What is the difference between an RTI error and an RTO error and how do I
calculate them for my error budget? Answer The AD8422 is composed of a preamplifier stage that applies differential…
Question The output range in my application is not as wide as the specification says.
What is wrong? Answer The AD8422 is a modified version of the 3 op-amp instrumentation amplifier,
which means that…
