Product Details

The ADA4062-2 and ADA4062-4 are dual and quad JFET-input amplifiers with industry-leading performance. They offer lower power, offset voltage, drift, and ultralow bias current. The ADA4062-2 B grade (SOIC package) features a typical low offset voltage of 0.5 mV, an offset drift of 4 μV/°C, and a bias current of 2 pA.

The ADA4062 family is ideal for various applications, including process control, industrial and instrumentation equipment, active filtering, data conversion, buffering, and power control and monitoring. With a low supply current of 165 μA per amplifier, they are well suited for lower power applications.

The ADA4062 family is also specified for the extended industrial temperature range of −40°C to +125°C. The ADA4062-2 is available in lead-free, 8-lead SOIC, 8-lead MSOP, and 10-lead LFCSP (1.6 mm × 1.3 mm × 0.55 mm) packages, and the ADA4062-4 is available in a lead-free, 14-lead TSSOP package.

    Tools & Simulations

    SPICE Model

    Design Tool

    Analog Filter Wizard

    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.

    Analog Photodiode Wizard

    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.
