The AD708 is a high precision, dual channel operational amplifier with very low offset voltage and drift, noise, and matching characteristics. It is suitable for applications that require high precision.
The AD708 is a dual monolithic operational amplifier offering exceptional DC precision. Each channel provides a maximum offset voltage of 30 µV and an offset voltage drift of 0.3 µV/°C, making it suitable for high‑gain, precision instrumentation applications. The device is available in several performance grades and package types, including 8‑lead PDIP, CERDIP, and hermetic CERDIP/883B.
Typical performance includes a minimum open‑loop gain of 5 million V/V, a CMRR of at least 130 dB, and a PSRR of at least 120 dB. The AD708 also features very low input voltage noise (0.35 µV p‑p from 0.1 Hz to 10 Hz) and robust ESD protection. Absolute maximum ratings and thermal characteristics are provided for reliable design across commercial, industrial, and military temperature ranges.
