Analog Devices has released a new electrometer-grade operational amplifier that enables chemical analysis instruments to achieve the highest level of precision and data repeatability over a wider temperature range in a compact solution that reduces overall bill of materials and design footprint.
The ADA4530-1 op amp achieves this with an input bias current that is at least 20 times lower than competing devices. Such low bias current makes the ADA4530-1 ideal for interfacing to sensors that are sensitive to output loading such as photo diodes and other high output impedance sensors often used in precision monitoring/analysis equipment such as spectrophotometers, chromatographs and mass spectrometers, as well as potentiostatic and amperostatic coulometry measurement devices.
The new amp also can be used as a front-end amplifier for picoammeter and coulombmeter instrumentation systems, as a transimpedance amplifier for photodiodes, ion chambers, and working electrode measurements, or as a high-impedance buffer for chemical and capacitive sensors.
Anglia and Analog Devices are hosting two in depth technical workshops in April. The workshops will focus on the exploration of the signal chain and techniques to quantify noise, signal conditioning of analog /digital converters.
