| 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 input, IN+, between 0 V to VREF 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 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.
