Tools & Simulations

LTspice 1

Models for the following parts are available in LTspice:

  • OP2177

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

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

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.

Product Details

The EVAL-AD7768FMCZ evaluation kit features the AD7768 24-bit, 256 kSPS, analog-to-digital converter (ADC). A 7 V to 9 V external bench top supply is regulated to 5 V and 3.3 V to supply the AD7768 and support components. The EVAL-AD7768FMCZ board connects to the USB port of the PC via a connection to the EVAL-SDP-CH1Z motherboard.

The AD7768 evaluation software fully configures the AD7768 device register functionality and provides dc and ac time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.

The EVAL-AD7768FMCZ is an evaluation board that allows the user to evaluate the features of the ADC. The user PC software executable controls the AD7768 over a USB cable through the EVAL-SDP-CH1Z System Demonstration Platform (SDP). The AD7768 evaluation software requires PC running Windows® 7 to Windows 10 with a USB 2.0 port.

Full specifications on the AD7768 are available in the product data sheet, which should be consulted in conjunction with this user guide when working with the evaluation board.
