Description:

• Silicon Labs' Si8920BD-IS current shunt monitor is a high-performance device that allows for precise current sensing and differential measurements.
• High-Voltage Isolation:
• Provides galvanic isolation, which protects low-voltage circuits from high-voltage spikes.
• The strong common-mode transient immunity of 75 kV/μs allows accurate readings in high-power switching settings such as motor drives or inverters.
• Input Voltage Range:
• Supports a differential input range of approximately ±200 mV.
• Output characteristics:
• Differential analog output is amplified by 8.1 or 16.2x.
• The signal latency is around 0.75 μs, ensuring rapid response.
• The output noise level is 0.10 mVrms over a 100 kHz bandwidth.
• Precision and stability:
• Low input offset of 0.2 mV.
• Less than 0.5% gain inaccuracy.
• Offset drift: 1 μV/°C.
• Gain drift: 10 ppm/°C.
• Excellent linearity at 0.025% Full Scale.
• Operating conditions:
• Operating temperature range is -40°C to +125°C.
• Package:
• Type: 16-Pin SOIC.
