Someone please tell me the difference between Single Supply and Dual Supply of Instrumentation Amplifier
Either the INA129 or the INA827 can use single or dual supplies. An instrumentation amplifier (like op amps) does not have an internal connection to ground.
If you interested in the single-supply operating region of the INA128/9, please download our INA Vcm vs. Vout tool (link below). You can select the INA128 and adjust the supplies as needed.
Also, you may be interested in our TI Precision Labs series, specifically the lecture about op amp input common-mode range and output swing. The link is www.ti.com/precision-labs.
