Product Details

The ADMX2001 is a measurement module that simplifies the development of impedance measurement systems or can be used to enhance the capabilities of existing test platforms. Using high-performance mixed-signal and processing algorithms, the ADMX2001 can measure changes in capacitance as small as 0.1fF and resistance values up to 20MΩ, often required to test semiconductor devices, electronic components, and sensors. Moreover, built-in measurement algorithms enable the ADMX2001 to deliver fully calibrated complex impedance or admittance measurement results in various formats, including parallel and series combinations of resistance, capacitance, and inductance.

Applications

  • Automated test equipment
  • Semiconductor characterization
  • Wafer acceptance test
  • Electrical Impedance Spectroscopy

ADSKPMB10-EV-FMCZ

Single-Channel, Fully Isolated, Low Latency Data Acquisition System (DAQ)

Buy Now View Details

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.

APPLICATIONS

  • Data acquisition and system monitoring
  • Automated test equipment
  • Instrumentation 
  • Medical equipment
