Zero-drift amplifier from Analog Devices claims industry's lowest voltage noise
April 13, 2011 // Paul Buckley
Analog Devices, Inc., has introduced what the company claims is the industry's lowest-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 design achieves an ultra-low integrated voltage noise of 99 nVp-p over 0.1 Hz - 10 Hz meaning that the ADA4528 delivers a 26 percent lower voltage noise at 40 percent less power consumption than the closest competing amplifiers. 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.
The 5.3-nV/rtHz voltage noise density allows designers for the first time to use the zero-drift amplifier in broadband applications, such as piezoelectric transducers and precision data acquisition systems.
The ADA4528 zero-drift amplifier offers low offset voltage of 2.5 µV max and the industry’s lowest guaranteed offset-voltage drift of 0.015 µV/˚C max. The device has a 140 dB gain and a CMRR (common-mode rejection ratio) of 135 dB and a 130 dB PSRR (power-supply rejection ratio), making it well-suited for precision amplification of low-level signals in applications such as position and pressure sensors, strain gages, and medical instrumentation. The ADA4528 is fully specified to operate from a 2.2-V to 5.5-V single-voltage supply over the extended industrial temperature range (−40 to +125°C) and is available in an 8-lead MSOP (Mini Small Outline Package).
