The AD708 is a high precision, dual monolithic operational amplifier. Each amplifier individually offers excellent dc precision with maximum offset voltage and offset voltage drift of 30 μV and 0.3 μV/°C respectively. The AD708 has a minimum open-loop gain of 5 million V/V, a minimum CMRR of 130 dB and a minimum PSRR of 120 dB.
The AD708 is a high precision, dual monolithic operational amplifier designed for applications requiring excellent DC precision. It features an ultra-low maximum offset voltage of 30 pV and low drift characteristics, making it ideal for constructing high-gain instrumentation amplifiers.
Available in four performance grades (AD708J, AD708A, AD708B, and AD708S), the device is offered in various packages including PDIP, CERDIP, and hermetic CERDIP/883B. The document provides comprehensive electrical specifications, absolute maximum ratings, typical performance characteristics graphs, and application circuit examples.
