ADA4075-2 Ultralow Noise Amplifier at Lower Power

APPLICATIONS

The ADA4075-2 is a dual high-performance low noise operational amplifier combining excellent dc and ac characteristics on ADI’s iPOLAR™ process. ADI’s proprietary iPolar process is an advanced bipolar technology implementing vertical junction isolation with lateral trench isolation, allowing for low noise performance amplifiers in smaller die size at faster speed and lower power. Its high slew rate, low input bias current, low distortion and ultra low noise make it ideal for high fidelity audio and high performance instrumentation applications, especially for lower power demands, small enclosure or high density applications. The ADA4075-2 is specified for the −40°C to +125°C temperature range and is available in a standard SOIC package and a 2 mm × 2 mm LFCSP package.
