ALD1722/ALD1722G
PRECISION LOW POWER CMOS OPERATIONAL AMPLIFIER
GENERAL DESCRIPTION
The ALD1722/ALD1722G is a monolithic precision low power CMOS 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. 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.
