Analog Devices OP285 Operational Amplifier Datasheet
The OP285 is a high‑speed, precision dual operational amplifier that combines the low‑noise performance of bipolar transistors with the speed of JFETs. It offers a typical offset voltage of 250 µV, a slew rate of 22 V/µs, and a gain‑bandwidth product of 9 MHz while consuming only about 5 mA supply current. The device is supplied in 8‑pin plastic DIP and SO‑8 surface‑mount packages and operates over an extended industrial temperature range (‑40 °C to +85 °C).
The datasheet includes detailed specifications, pin‑out diagrams, absolute maximum ratings, ordering information, and application notes such as short‑circuit protection, input over‑current protection, and fast settling performance for high‑speed A/D converter driving.
