Isolation amplifiers are components with dual
purposes of amplification & safety. It is equipped with a delta-sigma
analog-to-digital (AD) converter which helps in detecting infinitesimal
electric current & voltage fluctuation with high precision. It provides
grounding, insulation, and data isolation by providing a barrier of electrical
safety & electrical isolation. It protects the patients from leakage
currents and also protects data acquisition components from common mode
voltages. It is used for amplifying low-level signals in multi-channel
applications. It may include isolated power supplies for both the output and
input stages, or may use external or peripheral power supplies on each isolated
portion. It is commercially available as hybrid integrated circuits made by
numerous manufacturers. Some methods of providing isolation are optically
isolated amplifier, transformer-isolated amplifier and capacitive isolation
amplifier.
The key advantages are included high
linearity, high gain stability & linearity, avoids device & radiated
noise and conducted noise, improves patient safety, high common mode rejection
ratio and high accuracy.
According to study, “Global
Isolation Amplifier Market, By Application (Medical (ECG and EEG),
Industrial (Industrial Process Control, Current Shunt Measurement and Others
(Nuclear and Telecommunication)), By Type (Analog and Digital), By Region -
Forecast to 2023” the key companies operating in the global isolation amplifier
market are Silicon Laboratories, Inc., Wurth Elektronik, Dewetron GmbH, DRAGO
Automation GmbH, Broadcom Pte. Ltd., Toshiba Corporation, Analog Devices Inc.,
Eaton Corporation PLC, Texas Instruments Inc.
Based on type, isolation amplifier market is
segmented into digital and analog. The digital isolation amplifier segment is
anticipated to be the biggest revenue generator due to transition of customers
to faster data speed and change in communication networking technologies during
the forecast period. Based on product type, market is segmented into capacitor
isolated amplifiers, optoelectronic isolated amplifiers and transformer
isolated amplifiers (electromagnetic isolated amplifiers). In addition, based
on application, market is segmented into industrial, medical, sewage treatment,
nuclear (input/output/power isolation), electronics, telecommunication and
others. Industrial sector includes industrial process control, current shunt
measurement and others. Medical sector includes Electrocardiography (ECG),
electroencephalogram (EEG) and others. Medical segment dominates the market
owing to growth in demand for amplifiers in maintaining the stability of
equipment.
The isolation amplifier market is driven by
rise in concerns for patient safety in hospitals & medical institutions,
followed by growth in demand for noise cancellation & data protection in
telecommunication. However, high pricing of wide bandwidth 3-port isolation
amplifier for numerous industrial applications may impact the market. Moreover,
increase in adoption of isolated amplifier in optical isolation with fiber
optic transmission is a key opportunity for market.
Based on geography, the North-American region
holds major share in isolation amplifier market owing to rise in technological
advancements, increase in well-established industries such as
telecommunication, automotive, and healthcare sectors and growth in demands a
well-structured industry in the region. The European and Asian-Pacific regions
are estimated to witness higher growth rate due to high development in the
field of technology and presence of developing nations over the forecast
period. It is predicted that future of the market will be bright because of
presence of global players and rapid urbanization during the forecast period.
