AD203SN

AD203SN is a kind of 10 kHz bandwidth isolation amplifier. The typical applications include engine monitoring and control, mobile multichannel data acquisition systems, instrumentation and/or control signal isolation, current shunt measurements and high voltage instrumentation amplifiers.

There are some features as follows. First is characterized to the full military temperature range which is from -55 to +125. The second is 10 kHz full power bandwidth. Then is wide output range which is ±10 V min (into a 2.5k load). Next is high CMV isolation which is 1500 V RMS continuous. The fifth is isolated power which is ±15 V DC @ ±5 mA. The sixth is two-port isolation through transformer coupling. The last one is low nonlinearity which is ±0.025% max.

What comes next is about the specifications (typical @ +25, VS=+15 V dc, unless noted otherwise). First is about the input voltage ratings. The linear differential range is ±10 V. The maximum CMV input to output AC, 60 Hz, continuous is 1500 V rms. The maximum leakage current input to output is 4.0A rms at 240 V rms, 60 Hz. Then is about the rated output. The minimum voltage (OUT HI to OUT LO) @ RL=5.0 k is ±10 V. The output resistance is 0.2. The current is ±4 mA. The maximum capacitive load is 270 pF. The output ripple is 15 mV pk-pk at 100 kHz bandwidth and 0.7 mV pk-pk at 5 kHz bandwidth.
