These devices support up to 16 bipolar input channels +with independently selectable ranges and operate from a single 5V +analog supply. Key features include high input impedance, analog input +clamp protection, a first-order antialiasing filter, and an accurate +on-chip reference. They offer up to 1 MSPS throughput per channel pair +with 90.5 dB SNR, and up to 92 dB SNR with digital oversampling. The +AD7616 supports both serial and parallel interfaces, while the AD7616-P +supports only parallel. Additional capabilities include a flexible +channel sequencer, burst mode, CRC, and compatibility with various +digital communication protocols. The board is ideal for evaluating the +ADCs in applications such as power-line monitoring, motor control, +instrumentation, and data acquisition systems. + +Applications +------------- + +- Power line monitoring +- Protective relays +- Multiphase motor control +- Instrumentation and control systems +- Data acquisition systems + +Hardware Specifications +------------------------ + +Power Supply Requirements +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The EVAL-AD7616SDZ evaluation board requires an external power supply +via a DC barrel connector (J7) supporting 7V to 9V input to generate +VCC and VDRIVE voltages. Optional external supplies can be connected +through the VSUPPLY (5V to 10V) and VLOGIC (2.3V to 3.6V) connectors +for analog and digital supply rails, respectively. Correct link +configuration (as per Table 3 in the user guide) is necessary before +powering the board in any mode, whether standalone or controlled +by a controller board. + +On-board Connector +~~~~~~~~~~~~~~~~~~ + +========= =================================================== +Connector Function +J1 Analog inputs (V0A to V3A) +J2 Analog inputs (V4A to V7A) +J3 Analog inputs (V0A to V3B) +J4 Analog inputs (V4B to V7B) +J5 Digital input/output pins for debug/standalone mode +J6 External reference SMA input +J7 External power connector, 7V to 9V DC input +J8 External VDRIVE power connector +J9 External VCC power connector +J10 120-way connector for the EVAL-SDP-CB1Z +========= =================================================== + +No-OS Build Setup +----------------- + +Please see: `https://wiki.analog.com/resources/no-os/build` + +No-OS Supported Examples +------------------------ + +The initialization data used in the examples is taken out from the +`Project Data Source Path `__ + +Basic example +~~~~~~~~~~~~~ + +The basic example code in the AD7616 no-OS project showcases the setup +and data acquisition capabilities of the AD7616 ADC. Execution begins +with enabling instruction and data caches. The hardware components are +initialized using structures like ``spi_engine_init_param``, +``axi_clkgen_init``, and ``no_os_pwm_init_param`` to configure SPI +communication, clock generation, and PWM for data conversions. The +``ad7616_setup()`` function initializes the AD7616 with these +parameters. Data sampling varies based on the mode: +``ad7616_read_data_parallel()`` or ``ad7616_read_data_serial()`` is used +for parallel or serial mode, respectively. Data from channels A and B +are printed, and caches are disabled post-capture. This example +demonstrates the foundational operations of initializing and running the +AD7616 in a no-OS environment. + +No-OS Supported Platforms +------------------------- + +Xilinx +~~~~~~~ + +Hardware Used +^^^^^^^^^^^^^ + +- **EVAL-AD7616SDZ**: Evaluation board for the AD7616 ADC +- **ZedBoard**: Xilinx Zynq-7000 development board +- **SDP-I-FMC Interposer**: Interface board for connecting the EVAL-AD7616SDZ to the ZedBoard + +Connections +^^^^^^^^^^^ + +1.
