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 5K
source imbalance.
Input voltage noise is held to 0.3
μ
V, 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 10
μ
A. An independent
±
12VDC, 10mA supply in the input section with the same voltage
isolation as the amplifier, is used to power optional external circuitry.
