Hi!
We use the INA148 (differential amplifier with high common mode voltage), on a aeronautical equipment, to receive a differential signal from A/C (Air Craft).
The context gives us voltage withstand constraints and our INA148 is supplied under 10V single mode. The datasheet gives the maximum common mode voltage admissible for 5V->15V symmetrical supply but only 5V for single supply, all at 25°C. Specific parameter are given with an offset of Vs/2 and Vs=5V : CMVR=[-47.5V;+32.5V].
It would be more practical to get a complete graph of the maximum common mode voltages according to supply voltage levels, offset levels and also a temperature coefficient.
Anyway, do someone can tell me what are these maximums [-60 V;+55 V]?
Thank you
