  • Overview
    ISO121BG Product overview

    DESCRIPTION The ISO120 and ISO121 are precision isolation amplifiers 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, which results in excellent reliability and good high frequency transient immunity across the barrier. Both the amplifier and barrier capacitors are housed in a hermetic DIP. The ISO120 and ISO121 differ only in package size and isolation voltage rating. FEATURES ● 100% TESTED FOR PARTIAL DISCHARGE ● ISO120: Rated 1500Vrms ● ISO121: Rated 3500Vrms ● HIGH IMR: 115dB at 60Hz ● USER CONTROL OF CARRIER FREQUENCY ● LOW NONLINEARITY: ±0.01% max ● BIPOLAR OPERATION: VO = ±10V ● 0.3"-WIDE 24-PIN HERMETIC DIP, ISO120 ● SYNCHRONIZATION CAPABILITY ● WIDE TEMP RANGE: –55°C to +125°C (ISO120) APPLICATIONS ● INDUSTRIAL PROCESS CONTROL: Trans ducer Isolator for Thermocouples, RTDs, Pressure Bridges, and Flow Meters, 4mA to 20mA Loop Isolation ● GROUND LOOP ELIMINATION ● MOTOR AND SCR CONTROL ● POWER MONITORING ● ANALYTICAL MEASUREMENTS ● BIOMEDICAL MEASUREMENTS ● DATA ACQUISITION ● TEST EQUIPMENT
