High performance op amps are low power

The single-channel THS4531A and dual THS4532 differential amplifiers feature a low quiescent current of 230 µA per channel, a gain-bandwidth product of 27 MHz, and noise of 10 nV/root Hz. The amplifiers maximum offset voltage is just 0.4 mV and slew rate is 200 V/us.

The devices have a common-mode rejection ratio of 116 db typical, 90 db minimum and input bias current is 305 na maximum over -40° to 125°C. Open loop gain is 114 db and offset voltage drift of only 9 uV/C enable precision sensing and buffering. Supply voltage is 2.5  to 5.5 V, PSRR is 108 db, and they cost $1.21/$1.85 ea/1,000.
