NCS20061

The NCS20061 is a high-performance, low-power operational amplifier manufactured by onsemi, designed for precision analog signal conditioning in demanding applications. It features a wide supply voltage range from 2.7 V to 5.5 V, enabling flexible integration into both battery-powered and fixed-voltage systems. The device offers a high gain-bandwidth product of 10 MHz, ensuring excellent frequency response for filtering, amplification, and buffering tasks across a broad spectrum of signals. This op-amp provides rail-to-rail input and output capability, allowing maximum dynamic range utilization without signal clipping, which is especially beneficial in low-voltage sensor interfaces. It operates with a very low quiescent current of just 300 µA per channel, making it ideal for energy-sensitive applications such as portable medical devices, industrial sensors, and Internet of Things (IoT) nodes where power efficiency is critical. The NCS20061 includes built-in ESD protection and operates reliably over an extended temperature range from -40°C to +125°C, enhancing its suitability for harsh environments like automotive electronics and industrial automation. Its CMOS architecture ensures low offset voltage (typically 1 mV) and low drift, delivering consistent performance under varying conditions. Additionally, the device supports single-supply operation and has a unity-gain stable configuration, simplifying design and reducing external component count. Common applications include signal conditioning for strain gauges, thermocouples, and pressure sensors; active filters in audio processing circuits; and level-shifting in communication interfaces. It is also used in data acquisition systems where accuracy and low noise are essential. With a compact SOIC-8 package, the NCS20061 fits efficiently into space-constrained designs while maintaining robust thermal and mechanical performance. The part is fully qualified for automotive use (AEC-Q100 Grade 1), making it suitable for engine control units, telematics, and ADAS systems. Its combination of low power, high precision, and reliability positions the NCS20061 as a versatile solution for modern analog front-end designs in consumer, industrial, and automotive markets.
