The ADA4627-1/ADA4637-1 are wide bandwidth precision amplifiers featuring low noise, very low offset, drift, and bias current. The parts operate from ±5 V to ±15 V dual supply.

The ADA4627-1/ADA4637-1 provide benefits previously found in few amplifiers. These amplifiers combine the best specifications of precision dc and high speed ac op amps. The ADA4637-1 is a decompensated version of the ADA4627-1 and is stable at a noise gain of 5 or greater.

With a typical offset voltage of only 70 μV, drift of less than 1 μV/°C, and noise of only 0.86 μV p-p (0.1 Hz to 10 Hz), the ADA4627-1/ADA4637-1 are suited for applications where error sources cannot be tolerated.

The ADA4627-1/ADA4637-1 are specified for both the industrial temperature range of −25°C to +85°C and the extended industrial temperature range of −40°C to +125°C. The ADA4627-1 and ADA4637-1 are available in tiny 8-lead LFCSP and 8-lead SOIC packages.

The ADA4627-1/ADA4637-1 are members of a growing series of high speed, precision op amps offered by Analog Devices, Inc.

    ADSKPMB10-EV-FMCZ

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

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

    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 Detail

    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.
