GENERAL DESCRIPTION
The ALD1721/ALD1721G is a monolithic CMOS micropower high slew rate operational amplifier intended for a broad range of precision applications requiring exremely low input signal power. Input signal power is the product of input offset voltage and input bias current, which represents the minimum required power draw from the signal source in order to drive the input of the operational amplifier.
