Product Details
The ADA4627-1/ADA4637-1 are wide bandwidth precision amplifiers featuring low noise, very low offset, drift, and bias current. The parts operate from ±5 V to ±15 V dual supply.
The ADA4627-1/ADA4637-1 provide benefits previously found in few amplifiers. These amplifiers combine the best specifications of precision dc and high speed ac op amps. The ADA4637-1 is a decompensated version of the ADA4627-1 and is stable at a noise gain of 5 or greater.
With a typical offset voltage of only 70 μV, drift of less than 1 μV/°C, and noise of only 0.86 μV p-p (0.1 Hz to 10 Hz), the ADA4627-1/ADA4637-1 are suited for applications where error sources cannot be tolerated.
The ADA4627-1/ADA4637-1 are specified for both the industrial temperature range of −25°C to +85°C and the extended industrial temperature range of −40°C to +125°C. The ADA4627-1 and ADA4637-1 are available in tiny 8-lead LFCSP and 8-lead SOIC packages.
The ADA4627-1/ADA4637-1 are members of a growing series of high speed, precision op amps offered by Analog Devices, Inc.

Tools & Simulations
LTspice
LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.
Models for the following parts are available in LTspice:
ADA4627
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

Design Tools
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.
