TEXAS INSTRUMENTS  ISO122P  Isolation Amplifier, Precision, 1 Amplifier, 50 mV, 1500 Vrms, ± 4.5V to ± 18V, DIP, 8 Pins


Image is for illustrative purposes only. Please refer to product description.

Product Overview

The ISO122P is a precision Isolation Amplifier incorporating a novel duty cycle modulation-demodulation technique. The signal is transmitted digitally across a 2-pF differential capacitive barrier. With digital modulation the barrier characteristics do not affect signal integrity, thus 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 ISO122P is easy to use. No external components are required for operation.
  • 100% Tested for high-voltage breakdown
  • High IMR (140dB at 60Hz)
  • Bipolar operation - VO = ±10V
  • Fixed unity gain configuration
  • 0.020% Maximum nonlinearity
  • Green product


Industrial; Automation & Process Control; Test & Measurement
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
