ADA4528-2

5.0V Ultralow Noise, Zero-Drift, RRIO, Dual Op Amp
Manufactured by:

Product Details

The ADA4528-1/ADA4528-2 are ultralow noise, zero-drift operational amplifiers featuring rail-to-rail input and output swing. With an offset voltage of 2.5 μV, offset voltage drift of 0.015 μV/°C, and typical noise of 97 nV p-p (0.1 Hz to 10 Hz, AV = +100), the ADA4528-1/ADA4528-2 are well suited for applications in which error sources cannot be tolerated.

The ADA4528-1/ADA4528-2 have a wide operating supply range of 2.2 V to 5.5 V, high gain, and excellent CMRR and PSRR specifications, which make it ideal for applications that require precision amplification of low level signals, such as position and pressure sensors, strain gages, and medical instrumentation.

The ADA4528-1/ADA4528-2 are specified over the extended industrial temperature range (−40°C to +125°C). The ADA4528-1 is available in 8 lead MSOP and 8 lead LFCSP packages. The ADA4528-2 is available in an 8 lead MSOP package.

For more information about the ADA4528-1/ADA4528-2, see the AN-1114 Application Note, Lowest Noise Zero-Drift Amplifier Has 5.6 nV/√Hz Voltage Noise Density.

EVAL-AD7175-2 Circuit Diagram

Product Details

The EVAL-AD7175-2SDZ is a fully featured evaluation kit for the AD7175-2. This board operates in stand alone mode or in conjunction with the System Development Platform, EVAL-SDP-CB1Z . When operated with the System Development Platform software is provided enabling the user to perform detailed analysis of the ADC's performance. This software includes the technical note describing the operation and set up of the evaluation board in standalone operation or when operated with the System Development Platform . When operated in standalone mode the ADZS-BRKOUT-EX3 break out board is recommended for access to various control pins.

The SDP Controller board is a separate list item in the ordering guide below (EVAL-SDP-CB1Z). If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.

EVAL-AD7172-2 Circuit Diagram

Product Details

The EVAL-AD7172-2SDZ evaluation kit features the AD7172-2, a low power, 24-bit, 31.25 kSPS, Σ-Δ analog-to-digital converter (ADC) with true rail-to-rail buffers, on-board power supply regulation, and an external amplifier section for amplifier evaluation. A 7 V to 9 V ac-to-dc adapter is regulated to 5 V and 3.3 V; this supplies the AD7172-2 and support components. The EVAL-AD7172-2SDZ connects to a USB port via the SDP on the EVAL-SDP-CB1Z controller board.

The EVAL-AD7172-2SDZ evaluation software fully configures the AD7172-2 device functionality via a user accessible register interface and provides dc time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.

Full details about the device are available in the AD7172-2 data sheet, which should be consulted when using the EVAL-AD7172-2SDZ.
