The signal is transmitted • High IMR: 140 dB at 60 Hz digitally across a 2-pF differential capacitive barrier. With digital modulation the barrier characteristics do • Bipolar Operation: VO = ±10 V not affect signal integrity, thus resulting in excellent • 16-Pin Plastic DIP and 28-Lead SOIC reliability and good high-frequency transient immunity • Ease of Use: Fixed Unity Gain Configuration across the barrier. Both barrier capacitors are imbedded in the plastic body of the package. • 0.020% Maximum Nonlinearity • ±4.5-V to ±18-V Supply Range The ISO122 is easy to use. No external components are required for operation. The key specifications are 2 Applications 0.020% maximum nonlinearity, 50-kHz signal bandwidth, and 200-V/°C VOS drift. A power supply • Industrial Process Control: range of 4.5 V to 18 V and quiescent currents of 5 – Transducer Isolator, Isolator for mA on VS1 and ±5.5 mA on VS2 make the ISO122 Thermocouples, RTDs, Pressure Bridges, and ideal for a wide range of applications. Flow Meters, 4-mA to 20-mA Loop Isolation The ISO122 is available in 16-pin plastic DIP and • Ground Loop Elimination 28-lead plastic surface-mount packages. • Motor and SCR Control Device Information(1) • Power Monitoring PART NUMBER PACKAGE BODY SIZE (NOM) • PC-Based Data Acquisition PDIP (16) 17.90 mm × 7.50 mm • Test Equipment ISO122 SOIC (28) 20.01 mm × 6.61 mm (1) For all available packages, see the orderable addendum at the end of the data sheet. 4 Simplified Schematic 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
