The OP90 is a high performance, micropower op amp that operates from a single supply of 1.6 V to 36 V or from dual supplies of ±0.8 V to ±18 V. The input voltage range includes the negative rail allowing the OP90 to accommodate input signals down to ground in a single-supply operation. The OP90’s output swing also includes a ground when operating from a single-supply, enabling “zero-in, zero-out” configurations.
The OP90 is a high‑performance, micropower op‑amp that operates from a single supply of 1.6 V to 36 V or from dual supplies of 0.8 V to +18 V. Its input range includes ground, allowing true zero‑in/zero‑out operation, and it can deliver over 5 mA of output current while drawing less than 20 µA of quiescent current.
Typical applications include battery‑powered instruments, remote sensors and portable equipment where low voltage, low current and high precision are required. The datasheet provides detailed electrical characteristics, pin connections, ordering information and typical performance graphs.
