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 5K鈩?source imbalance.
Input voltage noise is held to 0.3碌V, 10Hz 鈥?1kHz rms. and current
noise to 4pA, 0.5Hz 鈥?1kHz rms. Input bias current is only 200pA, and
on the failure of any component is limited to 10碌A(chǔ). An independent
鹵12VDC,
10mA supply in the input section with the same voltage
isolation as the amplifier, is used to power optional external circuitry.
