The single ADA4077-1, dual ADA4077-2, and quad ADA4077-4 amplifiers feature extremely low offset voltage and drift, and low input bias current, noise, and power consumption. Outputs are stable with capacitive loads of more than 1000 pF with no external compensation.
Applications for this amplifier include sensor signal conditioning (such as thermocouples, resistance temperature detectors (RTDs), strain gages), process control front-end amplifiers, and precision diode power measurement in optical and wireless transmission systems. The ADA4077-1/ADA4077-2/ADA4077-4 are useful in line powered and portable instrumentation, precision filters, and voltage or current measurement and level setting.
Unlike other amplifiers, the ADA4077-1/ADA4077-2/ADA4077-4 have an MSL1 rating that is compliant with the most stringent of assembly processes, and they are specified over the extended industrial temperature range from −40°C to +125°C for the most demanding operating environments.
- Process control front-end amplifiers
- Optical network control circuits
- Precision sensors and controls
- Precision filters

Precision ADC Driver Tool
The Precision ADC Driver Tool is a web application that simulates the performance of precision ADC and driver combinations. Potential issues with driver selection, kickback settling, and distortion are flagged, and design tradeoffs can be quickly evaluated. Simulations and calculations include system noise, distortion, and settling of the ADC input
An online tool to illustrate range, gain and accuracy issues with Op Amp.
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.
