The EL8172 is compensated for a gain of 100 or more, and the EL8171 is compensated for a gain of 10 or more. The EL8171 and EL8172 have PMOS input devices that provide sub-nA input bias currents.
The amplifiers can be operated from one lithium cell or two Ni-Cd batteries. The EL8171 and EL8172 input range goes from below ground to slightly above positive rail. The output stage swings completely to ground (ground sensing) or positive supply - no pull-up or pull-down resistors are needed.
