Analog Devices Inc. ADA4528-1 & ADA4528-2 Precision Zero-Drift Op Amps

Analog Devices Inc. ADA4528-1 and ADA4528-2 Precision Zero-Drift Operational Amplifiers feature rail-to-rail input and output swing. Offering an offset voltage of 2.5μV, offset voltage drift of 0.015μV/°C, and typical noise of 97nVp-p (0.1Hz to 10Hz, AV = +100), the ADA4528-1/ADA4528-2 op amps are well suited for applications in which error sources cannot be tolerated.

The ADA4528-1 and ADA4528-2 Op Amps have a wide operating supply range of 2.2V to 5.5V, high gain, and excellent CMRR and PSRR specifications, making these devices ideal for applications that require precision amplification of low-level signals, such as position and pressure sensors, strain gauges, and medical instrumentation.

The Analog Devices Inc. ADA4528-1 and ADA4528-2 Op Amps are offered in LFCSP8 and MSOP8 packages.

  • Why Is DC Energy Metering Important?
    Driven by the development of efficient and economic power conversion technology based on wide bandgap semiconductors, such as GaN and SiC devices, many applications now see benefits in switching to DC energy exchange. As a consequence, precision DC energy metering is becoming relevant, especially where energy billing is involved.
