IA296
ULTRA LOW NOISE
TRUE INSTRUMENTATION
MEDICAL ISOLATION AMPLIFER
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
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.
