Range of data acquisition boards for quick prototyping
The AnalogMAX-DAQ1, AnalogMAX-DAQ2 and AnalogMAX-DAQ3 each combine an ADI high-performance precision data acquisition signal chain and power solution, an Intel MAX 10 FPGA and a memory subsystem comprising up to 64Mb 166MHz SDRAM, 64Mb Quad SPI Flash, and 4Kb EEPROM in a compact 86.5x25mm form factor. With a Micro USB receptacle, 23 GPIOs, and two SMA connectors, these platforms can be deployed in portable instrumentation and desktop equipment such as medical devices, as well as process-controllers and automated test equipment (ATE).
The AnalogMAX-DAQ1 is a high-accuracy programmable data-acquisition platform that integrates a complete precision signal chain for capturing high-frequency signals. This platform is based on the AD4003 18-bit 2Msample/s Easy Drive differential SAR ADC. An AD8251 10MHz programmable-gain instrumentation amplifier and AD8475 funnel amplifier provide low-noise gain and single-ended to differential signal conversion for driving the ADC. This platform can also be used with the pin-compatible AD4001, or AD4020 differential SAR ADC, offering users the choice of 16-, 18-, or 20-bit resolution and throughput from 500ksample/s to 2Msample/s.
The AnalogMAX-DAQ2 leverages the ADAQ798x 16-Bit μModule data acquisition SiP solution, which reduces end system component count by combining multiple common signal processing and conditioning blocks into a single device including a low-noise, high-bandwidth ADC driver, a stable reference buffer, and a high-accuracy 16-bit SAR ADC , and efficient power-management circuitry. This platform comes with an option of the 1Msample/s ADAQ7980 or 500ksample/s ADAQ7988 μModule, driven by an AD8251 instrumentation amplifier. The ADAQ798x also integrates critical passive components to ensure specified performance, enabling users to achieve over 90dB typical signal-to-noise ratio (SNR) and -105dB typical total harmonic distortion (THD).
The AnalogMAX-DAQ3 has been developed for use in high-end instrumentation in ATE and defence, as well as in high-performance industrial and medical applications. It features a fully differential, programmable instrumentation amplifier, LTC6373 driving the 20-/18-bit, 1.8/2Msample μModule data acquisition solution, ADAQ4020/4003 in order to address the demanding requirements of these target markets. The ADAQ4020/4003 μModule incorporates the critical passive components with superior matching and drift characteristics using Analog Devices’ proprietary iPASSIVES technology, which minimizes temperature dependent error sources and offers the optimized performance.
