Tel: 781.329.4700 Fax: 781.461.3113 www.analog.com Evaluation Board for the 8-/10-Lead Family of 14-/16-/18-Bit PulSAR ADCs The 8-lead PulSAR evaluation board covers the following 8-lead FEATURES PulSAR ADCs: AD7683 (16-bit), AD7684 (16-bit), and AD7694 Full featured evaluation board for 8-/10-lead PulSAR ADCs (16-bit). Versatile analog signal conditioning circuitry On-board reference, reference buffers, and ADC drivers These low power ADCs offer very high performance of up to PC software for control and data analysis of time and 18 bits with throughputs ranging from 100 kSPS to 1.33 MSPS. frequency domain The evaluation board is designed to demonstrate the performance System demonstration platform compatible (EVAL-SDP-CB1Z) of the ADCs and to provide an easy to understand interface for a variety of system applications. A full description of these EQUIPMENT NEEDED products is available in their respective data sheets, which Evaluation board (see Table 5) should be consulted when using this evaluation board. Wall adapter power supply The evaluation board is ideal for use with Analog Devices, Inc., Additional equipment needed system demonstration platform (SDP). This evaluation board SDP board (EVAL-SDP-CB1Z) (optional) interfaces to the SDP board via a 120-pin connector. SMA Precision source connectors, J6 and J10, are provided for the low noise analog Cable (SMA input to evaluation board) signal source. GENERAL DESCRIPTION On-board components include a high precision buffered band gap The 10-lead PulSAR evaluation board covers the following 5.0 V reference (ADR435), a signal conditioning circuit with two 10-lead PulSAR analog-to-digital converters (ADCs): AD7685 op amps (ADA4841-1), and a power supply to derive the necessary (16-bit), AD7686 (16-bit), AD7687 (16-bit), AD7688 (16-bit), voltage levels to supply all voltage needs. The 8-lead board also AD7690 (18-bit), AD7691 (18-bit), AD7693 (16-bit), AD7942 includes a level shifter (ADG3304) to interface the ADC with (14-bit), AD7946 (14-bit), AD7980 (16-bit), AD7982 (18-bit), the EVAL-SDP-CB1Z. AD7983 (16-bit), AD7984 (18-bit), AD7988-5 (16-bit), AD7989-5 (18-bit), AD7915 (16-bit) and AD7916 (16-bit).
