Product Details
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.

Design Tools
Use the Precision ADC Driver Tool to simulate the performance of precision ADC and driver combinations.
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
