The AD4000 / AD4001 / AD4002 / AD4003 / AD4020 family of evaluation boards enable 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 (see Figure 1) are ideal for use with the Analog Devices, Inc., high speed system demonstration platform (EVAL-SDP-CH1Z). These evaluation boards interface to the SDP-H1 board via a 120-pin connector. SMA connectors, JP2 and JP3, are provided for the low noise analog signal source.

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

The EVAL-AD4000FMCZ, EVAL-AD4001FMCZ, EVAL-AD4002FMCZ and EVAL-AD4003FMCZ are populated with the AD4000, AD4001, AD4002 and AD4003, respectively. However, these boards can be used to evaluate the performance of the AD4004, AD4005, AD4006, AD4007, AD4008, AD4010, and AD4011 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 its 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. Table 7 shows the models of the AD4000/AD4001/AD4002/AD4003/AD4020 evaluation boards.
