The OP270 is a high performance, monolithic, dual operational amplifier with exceptionally low voltage noise, 5 nV/÷Hz max at 1 kHz. It offers comparable performance to ADI’s industry standard OP27. The OP270 features an input offset voltage below 75 mV and an offset drift under 1 mV/∞C, guaranteed over the full military tem- perature range. Open-loop gain of the OP270 is over 1,500,000 into a 10 kW load, ensuring excellent gain accuracy and linearity.
The OP270 is a high‑performance, monolithic dual operational amplifier offering exceptionally low voltage noise (5 nV/√Hz at 1 kHz) and low input offset voltage (≤75 mV). It is suitable for high‑precision, high‑gain applications such as instrumentation amplifiers, dual buffers, and low‑noise active filters.
The device is supplied in standard 8‑lead DIP, 8‑lead CERDIP, 16‑lead SOIC and 16‑lead PDIP packages, with a supply voltage range up to ±18 V and a typical supply current of 4 mA. Detailed electrical specifications, absolute maximum ratings, and ordering information are provided in the datasheet.
