The OP‑42 is a fast, precision JFET‑input operational amplifier offering a 58 V/µs slew rate, 10 MHz gain‑bandwidth product, and low offset voltage. It is internally compensated for unity‑gain operation and consumes less than 6 mA supply current, making it suitable for high‑speed DAC output stages and sample‑and‑hold circuits.
The device is available in multiple packages (TO‑99, 8‑Pin Hermetic DIP, 8‑Pin Plastic DIP, 20‑Contact LCC, 8‑Pin SO) and meets stringent radiation‑hardness requirements for military and aerospace applications. Detailed electrical characteristics, typical performance curves, and ordering information are provided.
