GENERAL DESCRIPTION

The AD215 is a high speed input isolation amplifier designed to

isolate and amplify wide bandwidth analog signals. The innova-

tive circuit and transformer design of the AD215 ensures wide-

band dynamic characteristics while preserving key dc performance

specifications.

The AD215 provides complete galvanic isolation between the

input and output of the device including the user-available

front-end isolated power supplies. The functionally complete

design, powered by a 15 V dc supply, eliminates the need for a

user supplied isolated dc/dc converter. This permits the designer

to minimize circuit overhead and reduce overall system design

complexity and component costs.

The design of the AD215 emphasizes maximum flexibility and

ease of use in a broad range of applications where fast analog

signals must be measured under high common-mode voltage

(CMV) conditions. The AD215 has a 10 V input/output

range, a specified gain range of 1 V/V to 10 V/V, a buffered out-

put with offset trim and a user-available isolated front-end

power supply which produces 15 V dc at 10 mA.

PRODUCT HIGHLIGHTS

High Speed Dynamic Characteristics: The AD215 features

a typical full-power bandwidth of 120 kHz (100 kHz min), rise

time of 3 s and settling time of 9 s. The high speed perfor-

mance of the AD215 allows for unsurpassed galvanic isolation

of virtually any wideband dynamic signal.

FEATURES

Isolation Voltage Rating: 1,500 V rms

Wide Bandwidth: 120 kHz, Full Power (–3 dB)

Flexible Input and Buffered Output Stages: An uncommit-

ted op amp is provided on the input stage of the AD215 to

allow for input buffering or amplification and signal condition-

ing. The AD215 also features a buffered output stage to drive

low impedance loads and an output voltage trim for zeroing the

output offset where needed.

High Accuracy: The AD215 has a typical nonlinearity of

distortion is typically –80 dB at 1 kHz. The AD215 provides

designers with complete isolation of the desired signal without

loss of signal integrity or quality.

Excellent Common-Mode Performance: The AD215BY

(AD215AY) provides 1,500 V rms (750 V rms) common-mode

voltage protection from its input to output. Both grades feature

a low common-mode capacitance of 4.5 pF inclusive of the

dc/dc power isolation. This results in a typical common-mode

rejection specification of 105 dB and a low leakage current of

2.0 A rms max (240 V rms, 60 Hz).

Isolated Power: An unregulated isolated power supply of

the AD215. This permits the use of ancillary isolated front-end

amplifiers or signal conditioning components without the need

for a separate dc/dc supply. Even the excitation of transducers

can be accomplished in most applications.

Rated Performance over the –40 C to +85 C Temperature

Range: With an extended industrial temperature range rating,

the AD215 is an ideal isolation solution for use in many indus-

trial environments.
