Tools & Simulations

LTspice 1

Models for the following parts are available in LTspice:

  • ADA4098-1
  • ADA4098-2

Signal Chain Designer - BETA

Signal Chain Designer is a web-based tool designed to create and simulate complex precision signal chains. See your circuit’s performance before you commit to your PCB: transfer function, noise, power consumption, input range, and DC error. Quickly experiment with different parts and architectures. Signal chains can be exported to LTspice for further analysis.

Open 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.

Open Tool

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.

Product Details

The EVAL-ADA4098-1HUJZ evaluates the ADA4098-1 6-lead, thin small outline transistor (TSOT), robust Over-The-Top™ precision operational amplifier (op amp). The EVAL-ADA4098-1HUJZ is a prepopulated board using a gain of 1 configuration.

The EVAL-ADA4098-1HUJZ design allows simplified and efficient use. The EVAL-ADA4098-1HUJZ has edge mounted Subminiature Version A (SMA) connectors on the inputs and outputs to allow efficient connection to test equipment or other circuits. Bulk test points are also incorporated as an alternative option to be used for the inputs and outputs. The optimized EVAL-ADA4098-1HUJZ ground plane, component placement, and power supply allow maximum circuit flexibility and performance. The EVAL-ADA4098-1HUJZ combines surface-mount technology (SMT) with almost all 0805 size components to provide simplified installation and the option to replace and solder when needed, except for the bypass capacitors (C1 to C4) that are fixed 0603 sized. The EVAL-ADA4098-1HUJZ also has unpopulated resistor and capacitor pads that provide the user with options and flexibility to implement different application circuits and configurations.

Refer to the ADA4098-1 data sheet for full specifications, details on device operation, and application circuit configurations. Consult the data sheet in conjunction with the user guide when using the EVAL-ADA4098-1HUJZ.
