Advanced Linear Devices ALD2732PAL

The ALD2732A/ALD2732 is a precision dual low-cost low-power monolithic CMOS operational amplifier intended for a broad range of precision applications requiring extremely 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. Input signal power is also a figure of merit in source loading and its associated error, and is a measure of the basic signal resolution possible through the operational amplifier for a given signal source. For certain types of signal sources, signal loading directly translates into a significant distortion or "interface noise equivalent" term.
