Features and Benefits

  • Fully Isolated PMOD-to-FMC interposer board
  • Software programmable bipolar input ranges (±1.1 V to ±11.0 V)
    • Allows single-ended and differential signals
  • GΩ input impedance allows direct interface with sensors
  • On-board 5 V reference and buffer
  • Complete power management solution
  • SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface
  • PC software for control and data analysis of time and frequency domain

Product Details

The ADSKPMB10-EV-FMCZ signal chain kit is a two-board solution, which consists of a Precision Medium Bandwidth Data Acquisition Solution on a PMOD form factor and a Fully Isolated PMOD-to-FMC interposer board.

The Precision Medium Bandwidth Data Acquisition Solution features a discrete programmable gain instrumentation amplifier (PGIA) that was built using a 30V, High Speed, Low Noise, Low Bias Current, JFET Operational Amplifier, the ADA4627-1, a Precision Quad Matched Resistor Network, the LT5400, a Low Capacitance, 4-Channel, ±15 V/+12 V iCMOS™ Multiplexer, the ADG1209 and the internal Fully Differential Amplifier (FDA) ADC driver of the ADAQ4003. The PGIA in thru front-end offers high input impedance that allows direct interface with a variety of sensors. A programmable gain is often needed to adapt the circuit to different input signal amplitudes—unipolar or bipolar and single-ended or differential with varying common-mode voltages. The PGIA works with the ADAQ4003, an 18-Bit, 2 MSPS, µModule® Data Acquisition Solution.

The Fully Isolated PMOD-to-FMC interposer board was designed using a Low Noise, 1A, 1MHz Push-Pull DC/DC Driver with Duty Cycle Control, the LT3999, a Robust 3.0kVrms Digital Isolators w/ Fail-Safe for the SPI lines and PGIA gain control pins, the ADuM152N and the ADuM120N, and a Low noise and ultra-low noise LDO regulators the ADP7105 and the ADP150N respectively.

Product Details

The EVAL-1CH2CHSOICEBZ supports single and dual channel standard data isolators in 8 lead SOIC packages. The evaluation board provides a JEDEC standard 8-lead SOIC_N and SOIC_W pad layout. This supports signal distribution, loopback, and loads referenced to VDDx or GNDx, as well as optimal bypass capacitance. Signal sources can conducted to the board through header pins or through edge-mounted SMA connectors (not supplied with board). Terminal blocks provide for power connections. The board includes 200 mil header positions for compatibility with Tektronix active probes (not supplied with board).

The board follows best printed circuit board (PCB) design practices for 4-layer boards, including a full power and ground plane on each side of the isolation barrier. No other EMI or noise mitigation design features are included on this board. In cases of very high speed operation or when ultralow emissions are required, refer to the AN-1109 application note for additional board layout techniques.
