Analog Devices Inc. ADAQ23878 μModule Data Acquisition Solution

Analog Devices Inc. ADAQ23878 μModule Data Acquisition Solution reduces the development cycle of precision measurement systems. This solution accomplishes this by transferring the design burden of component selection, optimization, and layout from the designer to the device. The ADAQ23878 uses system-in-package (SIP) technology to reduce end system component count by combining multiple common signal processing and conditioning blocks in a single device. This includes a low noise, fully differential ADC driver amplifier (FDA), a stable reference buffer, and a high speed, 18-bit, 15 MSPS successive approximation register (SAR) ADC.

Features

  • Integrated fully differential ADC driver with signal scaling
    • Wide input common-mode voltage range
    • High common-mode rejection
  • Single-ended to differential conversion

    • Input ranges with 4.096V REFBUF: ±10V, ±5V, ±4.096V, ±2.5V, and ±1.5V
  • Gain/attenuation options: 0.37, 0.73, 0.87, 1.38, and 2.25
    • Critical passive components
    • 0.005% precision matched resistor array for FDA
  • 9mm x 9mm, 0.8mm pitch, 100-ball CSP_BGA package
    • 2.5x footprint reduction vs. discrete solution
  • Low power, dynamic power scaling, power-down mode
    • 143mW typical at 15 MSPS
  • Throughput 15 MSPS, no pipeline delay
  • INL error ±3.1ppm typical, ±6.2ppm maximum
    • (Gain = 0.73, gain = 0.87, gain = 1.38, gain = 2.25)
  • SINAD: 90.4dB typical at 20kHz (gain = 0.73)
  • THD −117dB at 1 kHz, −110dB at 100kHz (gain = 0.73)
  • Gain error ±0.005%FS typical
  • Gain error drift ±0.13 ppm/°C typical
  • Onboard reference buffer with VCMO generation
  • Serial LVDS interface
  • Wide -40°C to +85°C operating temperature range
