GENERAL DESCRIPTION
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. Manufactured with Advanced Linear Devices' enhanced EPAD® silicon gate CMOS process, the ALD1732A/ALD1732 is designed to set a new standard in low input signal power requirements. The typical input loading at its input is 0.03 mV offset voltage and 0.01 pA input bias current at 25C, resulting in 0.0003 fW input signal power draw. This input characteristic virtually eliminates any loading effects on most types of signal sources, offering unparalled accuracy and signal integrity and fidelity. The ALD1732A/ALD1732 is ideally suited for capacitive and high sensitivity, high impedance signal sources.
