The AD4000/AD4004/AD4008 are high accuracy, high speed, low power, 16-bit, precision successive approximation register (SAR) analog-to-digital converters (ADCs). These ADCs incorporate Easy Drive features, such as high-Z mode and an extended acquisition phase, which provide signal chain architectural flexibility by expanding the range of companion circuitry that can be paired with these ADCs.
Operating from a single power supply, VDD, these ADCs allow the reference voltage, VREF, to be applied externally and set independently of the supply voltage. With fast device throughput up to 2 MSPS, the AD4000/AD4004/AD4008 can accurately capture high-frequency signals and implement oversampling techniques to alleviate the challenges associated with antialias filter designs. Additionally, the power consumption of these ADCs scales linearly with throughput.
The AD4000/AD4004/AD4008 eliminate the need for a negative supply to the ADC driver amplifier by employing input span compression, while preserving access to the full ADC code range. Furthermore, the input overvoltage clamp protects the ADC inputs against overvoltage events, minimizing disturbances on the reference pin and eliminating the need for external protection diodes.
By reducing the serial peripheral interface (SPI) clock rate requirements, the AD4000/AD4004/AD4008 reduce digital input and output power consumption, broaden digital host options, and simplify the task of sending data across digital isolation. The SPI-compatible serial user interface supports 1.8 V, 2.5 V, 3.3 V, and 5 V logic by using the separate VIO logic supply.

EVAL-AD400x-FMCZ
Evaluation Board for the AD4000 Series 16-/18-/20-Bit Precision SAR ADCs
Product Detail
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 approx-imation 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 the Analog Devices, Inc., high speed system demonstration platform (SDP-H1). These evaluation boards interface to the SDP-H1 board via 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. Table 7 shows the models of the AD4000/AD4001/AD4002/AD4003/AD4020 evaluation boards.
