The AD4000/AD4001/AD4002/AD4003/AD4020 family of evaluation boards enables quick, simplified evaluation of the AD4000 family of 16-/18-/20-bit, precision successive approximation register (SAR) analog-to-digital converters (ADCs). The AD4000/AD4001/AD4002/AD4003/AD4020 are low power, 16-bit/18-bit/20-bit, precision SAR ADCs that offer high performance with throughputs up to 2 MSPS (1.8 MSPS for the AD4020). The evaluation board demonstrates the performance of the AD4000/AD4001/AD4002/AD4003/AD4020 family of ADCs and provides a simplified interface for a variety of system applications.

The EVAL-AD4000FMCZ/EVAL-AD4001FMCZ/EVAL-AD4002FMCZ/EVAL-AD4003FMCZ/EVAL-AD4020FMCZ evaluation boards, accessible from the EVAL-AD400x-FMCZ product page, are ideal for use with a field-programmable gate array (FPGA) mezzanine card (FMC) low pin count (LPC) connector.

On-board components include a high precision buffered band gap 5.0 V reference (ADR4550), a reference buffer (ADA4807-1), a common-mode buffer (ADA4807-1), a signal conditioning circuit with two op amps (ADA4807-1), and a power supply to derive the necessary voltage levels to supply all voltage needs.

The EVAL-AD4000FMCZ, EVAL-AD4001FMCZ, EVAL-AD4002FMCZ, EVAL-AD4003FMCZ, and EVAL-AD4020FMCZ are populated with the AD4000, AD4001, AD4002, AD4003, and AD4020, respectively. However, these boards can be used to evaluate the performance of the AD4004, AD4005, AD4006, AD4007, AD4008, AD4010, AD4011, AD4021, and AD4022 by limiting the sample rate in the evaluation software to the maximum sample rate of the specific ADC. For example, the AD4000 on the EVAL-AD4000FMCZ can be used to evaluate the performance of the AD4004 if the sample rate is limited to 1 MSPS. See the data sheet of each product for the corresponding evaluation board.

Full descriptions of these products are available in their respective data sheets, which must be consulted when using the corresponding evaluation board.

AD4020® - Easy Drive, Differential SAR ADC

ADR4550® - High precision buffered band gap 5.0 V reference

ADA4807-1® - Reference buffer

ADA4807-1® - Common-mode buffer

ADA4807-1® - Signal conditioning circuit with two op amps

Power Supply circuits

The develpment board comes with:

• Two 8GB SD cards:
  • One for Linux driver and IIO Scope (AD-FMC-SDCARD)
  • One for Windows-based GUI (AD400x®-SDCARD)

The block diagram of the EVAL-AD400x-FMCZ® Eval board (below) shows the major components.

The EVAL-AD400xFMCZ is a family of boards.

The EVAL-AD4000FMCZ/EVAL-AD4001FMCZ/EVAL-AD4002FMCZ/EVAL-AD4003FMCZ/EVAL-AD4020FMCZ evaluation boards support the AD4000BRMZ, AD4001BRMZ, AD4002BRMZ, AD4003BRMZ, and AD4020BRMZ devices respectively. However, these boards can be used to evaluate the performance of the AD4004, AD4005, AD4006, AD4007, AD4008, AD4010, AD4011, AD4021, and AD4022 by limiting the sample rate in the evaluation software to the maximum sample rate of the specific ADC. For example, the AD4000 on the EVAL-AD4000FMCZ can be used to evaluate the performance of the AD4004 if the sample rate is limited to 1 MSPS. See the data sheet of each product for the corresponding evaluation board.

The AD4020 expects the input signals to swing between GND and VREF. However, the EVAL-AD4020FMCZ board is set up to use the ADA4807 buffers which has its input offset by VCM. VCM is set to +2.5V. This means that the user is expected to provide a true differential input centered at GND, and the VCOM takes care of shifting it up.
