ADA4627-1/ADA4637-1是宽带宽精密放大器,具有低噪声和非常低的失调、漂移、偏置电流特性,采用±5 V至±15 V双电源供电。

ADA4627-1/ADA4637-1具备以前只有少数放大器才拥有的优势。并且集精密直流运放和高速交流运放的较佳性能规格于一体。ADA4637-1是ADA4627-1的非完全补偿版本,在噪声增益为5或更大时稳定工作。

ADA4627-1/ADA4637-1的典型失调电压仅70 μV,失调漂移不到1 μV/°C,噪声仅为0.86 μV p-p(0.1 Hz至10 Hz),因而适合用于不容许存在误差源的应用。

ADA4627-1/ADA4637-1的额定温度范围为−25°C至+85°C和−40°C至+125°C扩展工业范围。ADA4627-1采用8引脚LFCSP和8引脚SOIC封装,ADA4637-1采用小型8引脚SOIC封装。

ADA4627-1/ADA4637-1属于ADI公司不断扩展的高速精密运算放大器系列。

ADSKPMB10-EV-FMCZ

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

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

特性和优点

  • 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

产品详情

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.
