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.
