Tools & Simulations

LTspice

Models for the following parts are available in LTspice:

ADA4523-1

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

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.

Product Details

The AD-ACEVSE22KWZ-KIT is a reference design for the metrology subsystem plus selected other features of a level 2, 7 kW to 22 kW AC electric vehicle supply equipment (EVSE). It includes the ADE9113 isolated Σ-Δ analog-to-digital converter (ADC) coupled with the ADE9178 metrology DSP to accurately measure energy delivered to an electric vehicle (EV). It includes the MAX32672 ultralow- power ARM^® Cortex^®-M4 processor, a cost-effective, highly integrated, and highly reliable 32-bit microcontroller to accumulate energy measurements and securely send it to a host for display. A charge control state machine is run on the microcontroller to transition through different charge states when a charging plug is inserted into an electric vehicle. The kit includes a flexible printed circuit (FPC) connector and LCD to read the energy measurements and state transitions during a charging cycle. The power input/output, control pilot (CP), and proximity pilot (PP) signals are exposed on connectors at the edge of the board. The energy delivered to the EV is measured as a voltage drop across shunts and a resistor ladder network, which makes it easy to set up the boards in the field.
