Technical Specifications:

The NJM2746M operational amplifier is designed with internal phase compensation for stable operation in a wide range of feedback configurations. The input common-mode voltage range typically extends to the negative supply rail, allowing for ground-sensing applications. The output voltage swing is rail-to-rail, maximizing dynamic range. The amplifier is designed to minimize noise and distortion. It is typically used in signal conditioning circuits. The DMP8 package is designed for surface mounting, allowing for high-density packaging on printed circuit boards. Refer to the datasheet for detailed electrical characteristics, application circuits, and performance graphs.

The typical supply voltage is 5V, though it can operate from 3V to 12V. The input bias current is very low. The operating temperature range is usually -40°C to +85°C. The device is Pb-free and RoHS compliant. Detailed specifications, including slew rate and gain-bandwidth product, can be found in the official datasheet.
