➀ Temperature specification compensation of 125°C or more and low temperature drift
② it is possible from a common-mode input range of 0V with a single supply (assuming +5V) vs an output, and from an output of 0V to a minimum of 1.8V.
I am currently using the following devices in the range of +Vs = +5V in the 
AD8223, but they are in the same range.
③ SOIC8 pin preferably same as AD8223
Hi Taku-san,
The INA823 is one possibility available on the SOIC, pin compatible with the device you list above.
The device is specified over the extended temperature range -40C to +125C (but not above +125C).
Regarding the instrumentation amplifier linear range, the output of the instrumentation amplifier can get close to 0V at +150mV, but it cannot exactly reach 0V while powered with a +5V unipolar supply. This is true for the great majority of amplifiers due to the output swing limitations of the output stage while powered with unipolar supply. If you need to reach an exact 0V, the instrumentation amplifier will need to be powered with ±bipolar supplies.
You can verify the instrumentation amplifier output voltage range vs common-mode (VCM) using the Analog Engineer's Calculator, under "Amplifiers and Comparators" --> "INA Vcm vs Vout"
For example, with the INA823 with VS+ = +5V, VS- = 0V, if IN(-) is grounded, Gain = 1V/V, VREF=0V, and IN(+) = 1.8V, the input common-mode is Vcm= [(IN+) + (IN-)] / 2 = 0.9V, and the output range is limited to 0.15V (minimum), up to +2.1V.
- What is the Gain and Reference pin voltage?
- Please clarify if this application requires the IN- referred to GND. Please note, this is different than VCM = 0V, where VCM is defined as the average of the instrumentation amplifier inputs: Vcm= [(IN+) + (IN-)] / 2.
Thank you and Regards,
Luis
