-For component evaluation and performance purposes, as opposed to quick prototyping,​ the user is directed to Analog Devices [[/​resources/​eval/​sdp|System Demonstration Platform]] (**SDP**). The **SDP** consists of a: +{{page>common_sdp}}
-  * a controller board, like the **[[resources/​eval/​sdp/​sdp-b|EVAL-SDP-CB1Z]] (SDP-B)** +
-  * a compatible Analog Devices SDP [[adi>sdp#​exallist|product evaluation board]] +
-  * corresponding PC software +
-The EVAL-SDP-CB1Z controller board is part of Analog Devices SDP providing USB 2.0 high-speed connectivity to a PC computer running specific component evaluation software. ​ Each SDP evaluation daughter board includes the necessary installation files needed for this performance testing. It's expected that the analog performance on the two platforms may differ.+

-The [[adi>​AD7988-5]] ​is a 16-bit, successive approximation,​ analog-to-digital ​converter ​(ADC) that operate from a single power supply, VDD. The AD7988-5 offers a 500kSPS ​throughput. ​It is a low power, 16-bit sampling ​ADC with a versatile serial interface port. On the CNV rising edge, it samples ​an analog input IN+ between 0 V to REF with respect to a ground sense IN-. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD.+The [[adi>​AD7988-1]]/​[[adi>​AD7988-5]] ​are 16-bit, successive approximation,​ analog-to-digital ​converters ​(ADC) that operate from a single power supply, VDD. The AD7988-1 offers a 100 kSPS throughput, and the AD7988-5 offers a 500 kSPS throughput. ​They are low power, 16-bit sampling ​ADCs with a versatile serial interface port. On the CNV rising edge, they sample ​an analog inputIN+between 0 V to VREF with respect to a ground senseIN. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD. The SPI-compatible serial interface also features the ability to daisy-chain several ADCs on a single 3-wire bus using the SDI input. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic using the separate supply, VIO. The AD7988-1/​AD7988-5 generics are housed in a 10-lead MSOP or a 10-lead LFCSP (QFN) with operation specified from −40°C to +125°C.
  
 The EVAL-AD7988-5SDZ evaluation board is a member of a growing number of boards available for the SDP. It was designed to help customers evaluate performance or quickly prototype new AD7988-5 circuits and reduce design time. When using this evaluation board with the SDP board or Xilinx KC705 board, apply +7.5V as +Vs, a voltage between -2V and -5V as -Vs and +2.5V as VDD. The EVAL-AD7988-5SDZ evaluation board is a member of a growing number of boards available for the SDP.
