A customer had a question on the AD8222. A number of parts had shown offset and gain fluctuations over normal operating temperature, placing them out of specification. The customer asked whether the "plastic glass transition temperature" of 130°C requires a new soldering profile to avoid damage, as compared to the standard LFCSP profile shown in AN-772.
Also, no stock was seen for "no thermal pad" version (H option). The customer wanted to verify this variation was currently offered.
