The ADA4250 is an instrumentation amplifier with SPI/pin-strap progammable gains that is optimized for ultra-low power systems. With a minimum supply voltage of 1.7V, 26uA of quiescent current, a shutdown mode, a sleep mode, and a fast wake up settling time, ADA4250 can be power cycled on a battery powered system for even futher savings.
