AD210BN Isolation Amplifiers SOLATION AMPLIFIER IC 

DESCRIPTION

The AD210 is the latest member of a new generation of lowcost, high performance isolation amplifiers.

This three-port,wide bandwidth isolation amplifier is manufactured with surface-mounted components

in an automated assembly process.The AD210 combines design expertise with state-of-the-artmanufacturing

technology to produce an extremely compactand economical isolator whose performance and abundant

userfeatures far exceed those offered in more expensive devices.The AD210 provides a complete isolation

function with bothsignal and power isolation supplied via transformer coupling internal to the module.

The AD210’s functionally complete design, powered by a single +15 V supply, eliminates the need foran

external DC/DC converter, unlike optically coupled isolationdevices. The true three-port design structure

permits theAD210 to be applied as an input or output isolator, in single ormultichannel applications.

The AD210 will maintain its highperformance under sustained common-mode stress.Providing high

accuracy and complete galvanic isolation, theAD210 interrupts ground loops and leakage paths, and

rejectscommon-mode voltage and noise that may other vise degrademeasurement accuracy. In addition,

the AD210 provides protection from fault conditions that may cause damage to othersections of a

measurement system.
