Convert real-world physical quantities into digital data with AD7124-8 and PIC32MZ2048EFH100

ISO ADC 6 Click is based on the AD7124-8, an 8-channel, low noise, low power, 24-bit, sigma-delta ADC, and the ADuM341E, a 5kVrms quad digital isolator, both from Analog Devices. The ADC incorporates a sigma-delta modulator, buffer, reference, gain stage, and on-chip digital filtering. It is intended to measure wide dynamic ranges, weigh scales, temperature measurement applications, and low-frequency signals. The ADC allows up to 16 configurations or channels consisting of analog inputs, reference inputs, or power supplies. All ADC channels are available over the A0-15 header, with a common GND, power supply, and a bridge power switch (PSW). You can add an external reference over the REF+ and REF-

pins. The internal reference has its output available over the REFOUT pin. The synchronization input is also available over the SNC pin. It allows synchronization of the digital filters and analog modulators when using several AD7124-8 devices. For this purpose, the internal clock is available over the CLK pin. Alternatively, the internal clock can be turned off, and this pin can provide an external clock, allowing simultaneous conversions. The isolator isolates the ADC communication lines to the host MCU. It features low propagation delay, low dynamic power consumption, 100Mbps maximum guaranteed data rate, and more. The isolator is based on CMOS, a monolithic air core transformer technology, and iCoupler technology.

ISO ADC 6 Click uses a standard 4-wire SPI serial interface of the ADC to communicate with the host MCU over the isolator barrier. The isolator uses a high-frequency carrier to transmit data across the isolation barrier using iCoupler chip scale transformer coils separated by layers of polyimide isolation. The ADC can work in three power modes, which allows sampling in a range of 1.17sps up to 19200sps. This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.

Flip&Click PIC32MZ is a compact development board designed as a complete solution that brings the flexibility of add-on Click boards™ to your favorite microcontroller, making it a perfect starter kit for implementing your ideas. It comes with an onboard 32-bit PIC32MZ microcontroller, the PIC32MZ2048EFH100 from Microchip, four mikroBUS™ sockets for Click board™ connectivity, two USB connectors, LED indicators, buttons, debugger/programmer connectors, and two headers compatible with Arduino-UNO pinout. Thanks to innovative manufacturing technology,

it allows you to build gadgets with unique functionalities and features quickly. Each part of the Flip&Click PIC32MZ development kit contains the components necessary for the most efficient operation of the same board. In addition, there is the possibility of choosing the Flip&Click PIC32MZ programming method, using the chipKIT bootloader (Arduino-style development environment) or our USB HID bootloader using mikroC, mikroBasic, and mikroPascal for PIC32. This kit includes a clean and regulated power supply block through the USB Type-C (USB-C) connector. All communication

methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, user-configurable buttons, and LED indicators. Flip&Click PIC32MZ development kit allows you to create a new application in minutes. Natively supported by Mikroe software tools, it covers many aspects of prototyping thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.
