I have the datasheet revision M. The GBW is specified as 1.4 MHz but all the gain charts seems around a 10-fold lower. In Figures 6, 7, 8 and 9, no one show a zero dB gain over 1Mhz. It is more ranging from 400 kHz to 800 kHz. Since the datasheet have reached rev. M., I guess there is something I do not understand to explain this apparent discrepancy. Please explain! Thank you!
