Zero Drift Amplifier for Medical Applications:Analog Devices
Semiconductor producer Analog Devices Inc. (ADI) has introduced its low-noise, zero-drift operational amplifier. The ADA4528 zero-drift op amp is designed for instrumentation and medical applications that require precision over time and temperature without system calibration. The breakthrough design achieves an ultra-low integrated voltage noise of 99 nVp-p over 0.1 – 10 Hz meaning that the ADA4528 delivers a 26% lower voltage noise at 40% less power consumption than the closest competing amplifiers, according to the company. This improves system SNR (signal-to-noise ratio) and lowers the noise floor, enabling 24-bit resolution over 150 kHz in A/D converters while improving system accuracy.
