ISO113B

® ISO113 ISO 113 Low-Cost, High-Voltage, Internally Powered OUTPUT ISOLATION AMPLIFIER FEATURES DESCRIPTION ● SELF-CONTAINED ISOLATED SIGNAL AND OUTPUT POWER ● SMALL PACKAGE SIZE: Double-Wide (0.6") Sidebraze DIP ● CONTINUOUS AC BARRIER RATING: 1500Vrms ● WIDE BANDWIDTH: 20kHz Small Signal, 20kHz Full Power ● BUILT-IN ISOLATED OUTPUT POWER: ±10V to ±18V Input, ±50mA Output ● MULTICHANNEL SYNCHRONIZATION CAPABILITY ● BOARD AREA ONLY 0.72in.2 (4.6cm2) The ISO113 output isolation amplifier provides both signal and output power across an isolation barrier in a small double-wide DIP package. The ceramic nonhermetic hybrid package with side-brazed pins contains a transformer-coupled DC/ DC converter and a capacitor-coupled signal channel. APPLICATIONS ● ● ● ● ● 4mA TO 20mA V/I CONVERTERS MOTOR AND VALVE CONTROLLERS ISOLATED RECORDER OUTPUTS MEDICAL INSTRUMENTATION OUTPUTS GAS ANALYZERS Extra power is available on the isolated output side for driving external loads. The converter is protected from shorts to ground with an internal current limit, and the soft-start feature limits the initial currents from the power source. Multiple-channel synchronization can be accomplished by applying a TTL clock signal to paralleled Sync pins. The Enable control is used to turn off transformer drive while keeping the signal channel modulator active. This feature provides a convenient way to reduce quiescent current for low power applications. The wide barrier pin spacing and internal insulation allow for the generous 1500Vrms continuous rating. Reliability is assured by 100% barrier breakdown testing that conforms to UL1244 test methods. Low barrier capacitance minimizes AC leakage currents. These specifications and built-in features make the ISO113 easy to use, and provides for compact PC board layout. +VCC1 V IN Duty Cycle Demodulator Duty Cycle Modulator –VCC1 Sync Com 1 Sync* Enable +VC Sense V OUT Gnd 2 –VC +VCC2 Oscillators, Driver Rectifiers, Filters Ps Gnd –VCC2 Gnd 1 *Ground if not used International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.

Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
