Precision Amplifiers (VOS < 1 mV, Bandwidth < 50 MHz)
Zero-Drift Amplifiers
ADA4528-1: Precision, Ultralow Noise, RRIO, Zero-Drift Op Amp
The ADA4528-1 is an ultralow noise, zero-drift operational amplifier featuring rail-to-rail input and output swing. With an offset voltage of 2.5 mV, offset
voltage drift of 0.015 mV/°C, and noise of 97 nV p-p (0.1 Hz to 10 Hz, AV = +100), the device is well suited for applications in which error sources cannot
be tolerated. With wide operating supply range of 2.2 V to 5.5 V, high gain and excellent CMRR and PSRR specifications, the ADA4528-1 is ideal for
precision amplification of low level signals, such as position and pressure sensors, strain gages, and medical instrumentation.
