Com plete, Single D evice Solution for Input Isolation

T he AD102 offers full isolation without external parts or need

for an external dc/dc power source. T he AD104 features the

same functionality at a lower price for multichannel uses when

supplied with a 25 kHz clock signal.

T he AD102 and AD104 are general purpose, two-port, isolation

amplifiers suitable for use where input signal isolation is desired.

Each offers a functionally complete, compact isolation solution

rated at 500 V rms common mode, based upon the proven and

reliable transformer-coupled, galvanic isolation technique used

in all AD200 series isolation amplifier products.

H igh Accur acy

Each model is offered in a minimum footprint package requiring

no external components to operate. T hough similar to the

AD202 and AD204, the AD102 and AD104 models are in-

tended as lower cost solutions where the performance of the

AD202 or AD204 is not demanded.

A maximum nonlinearity of 0.05% is specified for both the

AD102 and AD104 over the rated temperature range.

Wide Bandwidth

Each is specified with a full power (–3 dB) bandwidth. T he

AD104 at 4 kHz and the AD102 at 1.5 kHz.

Both the AD102 and AD104 can be used in applications where

input-to-input and/or input-to-system isolation is desired. T he

AD102 is best suited for single input uses as it requires only

+15 V dc power to operate. It may also be appropriate for

multichannel applications when input-to-input isolation is not

required such as where a single input multiplexer selects a spe-

cific channel prior to isolation.

H igh P er for m ance Com m on-Mode Rejection

While providing continuous 500 V rms isolation, greater than

100 dB rejection is provided. Each part has only 5.5 pF (typical)

of common-mode input capacitance.

Uncom m itted Input Stage

Both models offer an uncommitted op amp input stage for user

flexibility and input gain optimization up to 100 V/V.

For applications where input to input isolation is required, the

AD104 may be a more desirable choice. It offers the lowest cost

per channel especially when powered from a common clock

source, the cost of which may be amortized over many channels.

Low P ower Consum ption

T he AD104 consumes only 35 mW from the clock source, the

AD102 only 75 mW from the +15 V dc supply.

T he clock necessary for AD104 operation is a 25 kHz, 15 V p-p

square wave applied to the clock input pin. Most standard oscil-

lator components like a CD4047 or T L555 may be used, or a

designer may choose the AD246 clock driver developed for the

AD204 product.
