DESCRIPTION

The ISO122 is a precision isolation amplifier incor-

porating a novel duty cycle modulation-demodulation

technique. The signal is transmitted digitally across

a2pFdifferentialcapacitivebarrier. Withdigitalmodu-

lation the barrier characteristics do not affect signal

integrity, resultinginexcellentreliabilityandgoodhigh

frequency transient immunity across the barrier. Both

barrier capacitors are imbedded in the plastic body of

the package.

V_OUT

The ISO122 is easy to use. No external components

are required for operation. The key specifications are

0.020% max nonlinearity, 50kHz signal bandwidth,

and 200µV/°C V_OSdrift. A power supply range of

±4.5V to ±18V and quiescent currents of ±5.0mA on

V_S1and ±5.5mA on V_S2make these amplifiers ideal

for a wide range of applications.
