This document describes the features and characteristics of the OP295/OP495 dual/quad rail-to-rail operational amplifiers. These amplifiers have single-supply operation, rail-to-rail output swing, low offset voltage, high gain bandwidth product, high open-loop gain, unity-gain stability, and low supply current. They are suitable for applications such as battery-operated instrumentation, servo amplifiers, actuator drives, sensor conditioners, and power supply control.
The OP295 and OP495 are dual/quad rail‑to‑rail operational amplifiers designed for single‑supply operation from 3 V to 36 V. They feature ultra‑low offset voltage (300 pV), low supply current (150 pA per amplifier), a gain‑bandwidth product of 75 kHz, and a unity‑gain stable open‑loop gain of 1000 V/mV. These characteristics make them suitable for battery‑operated instrumentation, sensor conditioning, and driving power transistors or H‑bridges.
Both devices are offered in multiple surface‑mount and through‑hole packages. The OP295 is available in 8‑lead PDIP and 8‑lead SOIC_N packages, while the OP495 comes in 14‑lead PDIP and 16‑lead SOIC_W packages. The ordering guide lists temperature ranges, package descriptions, and part numbers for each variant.
