Texas Instruments ISO124

the iso124 is a precision isolation amplifier incorporating a novel duty cycle modulation-demodulation technique. the signal is transmitted digitally across a 2pf differential capacitive barrier. with digital modulation the barrier characteristics do not affect signal integrity resulting in excellent reliability and good high-frequency transient immunity across the barrier. both barrier capacitors are imbedded in the plastic body of the package. the iso124 is easy to use. no external components are required for operation. the key specifications are 0.010% max nonlinearity 50khz signal bandwidth and 200v/c vos drift. a power supply range of 4.5v to 18v and quiescent currents of 5. view all in datasheet
