Product Details
Top Features
- Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
- Small footprint package suitable for space-constrained applications
- 1 mΩ primary conductor resistance for low power loss
- High isolation voltage, suitable for line-powered applications
- User-adjustable Overcurrent Fault level
- Overcurrent Fault signal typically responds to an overcurrent condition in <2 µs
- Integrated shield virtually eliminates capacitive coupling from current conductor to die due to high dV/dt voltage transients
- Filter pin capacitor improves resolution in low bandwidth applications
- 3 to 5.5 V, single supply operation
- Factory-trimmed sensitivity and quiescent output voltage
- Chopper stabilization results in extremely stable quiescent output voltage
- Ratiometric output from supply voltage
