Low-power, low-noise Analog Devices ICs and Intel MAX 10 FPGA in compact 86.5mm x 25mm outline
Analog Devices and Arrow Electronics have worked with Trenz Electronic GmbH to produce three ready-to-use data-acquisition platforms that relieve design and manufacturing challenges for developers of professional measurement instruments.
The AnalogMAX-DAQ1, AnalogMAX-DAQ2 and AnalogMAX-DAQ3 each combine an Analog Devices’ 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 86.5mm x 25mm 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 Analog Devices’ AD4003 18-bit 2Msample/s Easy Drive differential SAR ADC (analog-to-digital converter). 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 Analog Devices ADAQ798x 16-Bit μModule data acquisition System-in Package (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).
