EVAL-AD7405FMCZ

16-Bit, Isolated Sigma-Delta Modulator, LVDS Interface.

Overview

The EVAL-AD7405FMCZ is a full featured evaluation board designed to allow the user to easily evaluate all features of the AD7405 isolated analog-to-digital converter (ADC). The evaluation board can be controlled by the EVAL-SDP-CH1Z via FMCZ connector (J9). The SDP-H1 board (EVAL-SDP-CH1Z) allows the evaluation board to be controlled through a USB port of a PC using the evaluation board software available for download from the product page or from the included installer CD.

Features:

• 5 MHz to 20 MHz external clock input rate

• 16 bits, no missing codes

• Signal-to-noise ratio (SNR): 88 dB typical

• Effective number of bits (ENOB): 14.2 bits typical

• Typical offset drift vs. temperature: 1.6 µV/°C

• Low voltage differential signaling (LVDS) interface

• On-board digital isolator

• On-board reference

• Full-scale analog input voltage range: ±320 mV

• −40°C to +125°C operating temperature range

• High common-mode transient immunity: >25 kV/µs

• 16-lead, wide-body SOIC_IC, with increased creepage package

• Safety and regulatory approvals

Applications:

• Shunt current monitoring

• AC motor controls

• Power and solar inverters

• Wind turbine inverters

• Data acquisition systems

• Analog-to-digital and opto-isolator replacements

Recommendations

People who follow the flow that is outlined, have a much better experience with things. However, like many things, documentation is never as complete as it should be. If you have any questions, feel free to ask on our EngineerZone forums, but before that, please make sure you read our documentation thoroughly.

To better understand the AD7405, we recommend to use the EVAL-AD7405FMCZ evaluation boards.

Warning

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
