The MAX410, MAX412 and MAX414 are single‑, dual‑ and quad‑package operational amplifiers designed for high‑speed, low‑voltage systems. They offer a very low input voltage‑noise density (≤ 2.4 nV/√Hz at 1 kHz) while operating from a supply range of +2.4 V to +5 V and drawing only 2.5 mA per amplifier.
Key electrical characteristics include a 28 MHz unity‑gain bandwidth, 4.5 V/µs slew rate, 7.3 Vpp output swing into a 2 kΩ load, and robust protection features such as a 35 mA short‑circuit output current limit. The devices are supplied in DIP, SO and CERDIP packages and are suited for low‑noise frequency synthesizers, audio amplifiers, instrumentation, and bridge signal‑conditioning circuits.
