Tools & Simulations

LTspice 3


Models for the following parts are available in LTspice:

  • AD8676

SPICE Model 1

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.

Open Tool

EVAL-ADMX1002

Ultra-low Distortion Signal Generator Measurement Module

Features and Benefits

  • Ultra-low distortion, high-resolution source
    • DC, 50Hz to 40kHz Frequency Range
    • Proprietary digital pre-distortion (DPD) algorithm
    • –130dBc THD @ 1kHz (typ.)
    • Arbitrary waveform generation (AWG) with on-board pattern memory
    • Differential (balanced) output up to 3.6VRMS
  • Fast pattern switching between multiple stored waveforms
  • Small form-factor (60mm x 40mm)
  • Low power, 1W typ. (quiescent)
  • SPI interface for integration into test and measurement systems

Product Details

The ADMX1002 is an ultra-low distortion sinewave and high-resolution arbitrary waveform generator. This high-performance module demonstrates a proprietary digital pre-distortion algorithm that reduces signal distortion below levels that can be achieved with high-performance digital-to-analog converters (DAC) and amplifiers alone. Its differential output can be set to common-mode levels often required to test high-performance analog-to-digital converters (ADC), audio codecs, and other audio ICs and systems. With an easy-to-use SPI interface and small-form factor, the ADMX1002 can be easily embedded into test systems, or simply used on the bench for measurement and characterization.

APPLICATIONS

  • High-end audio test
  • Analog-to-digital converter characterization and test
  • Sensor and transducer test
  • Frequency response and network analysis
  • ATE

    • Proprietary digital pre-distortion (DPD) algorithm
    • –130dBc THD @ 1kHz (typ.)
    • Arbitrary waveform generation (AWG) with on-board pattern memory
    • Differential (balanced) output up to 3.5VRMS
    • Fast pattern switching between multiple stored waveforms
  • Fully Differential input Acquisition Channel
  • Small form-factor (60mm x 40mm)
  • Low power, 1W typ. (quiescent)
  • SPI interface for integration into test and measurement systems

Product Details

The ADMX1001 is an ultra-low distortion sinewave and high-resolution arbitrary waveform generator with an acquisition channel. This high-performance module demonstrates a proprietary digital pre-distortion algorithm that reduces signal distortion below levels that can be achieved with high-performance digital-to-analog converters (DAC) and amplifiers alone. Its differential output can be set to common-mode levels often required to test high-performance analog-to-digital converters (ADC), audio codecs, and other audio ICs and systems. The signal generator and the acquisition channel can be individually controlled using separate, easy to use, SPI interfaces - combined with the module's small-form factor, the ADMX1001 can be easily embedded into test systems, or simply used on the bench for measurement and characterization.

APPLICATIONS

  • High-end audio test
  • Analog-to-digital converter characterization and test
  • Sensor and transducer test
  • Frequency response and network analysis
  • ATE
