FEATURES
- UL Component Recognized
- Ultra Low Noise
- Failure of Any Internal Component Results in <10µA Bias Current
- Excellent CMRR: 170 dB; 160 dB with 5KΩ Source Imbalance
- External Sync Capability BLOCK DIAGRAM IA296 The Model IA296 Isolation Amplifier features very high input / output isolation and very low noise. It can operate at common mode input voltages up to 5000 VDC continuous; CMRR is 170 dB with balanced source impedance, and 160 dB with 5KΩ source imbalance. Input voltage noise is held to 0.3µV, 10Hz – 1kHz rms. and current noise to 4pA, 0.5Hz – 1kHz rms. Input bias current is only 200pA, and on the failure of any component is limited to 10µA. An independent ±12VDC, 10mA supply in the input section with the same voltage isolation as the amplifier, is used to power optional external circuitry.
