Features

• Patented integrated digital temperature compensation circuitry allows for near closed loop accuracy over temperature in an open loop sensor
• UL60950-1 (ed. 2) certified
- Dielectric Strength Voltage = 2.4 kVrms
- Basic Isolation Working Voltage = 420 Vpk/297 Vrms
• Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
• Pin-selectable band width: 80 kHz for high bandwidth applications or 20 kHz for low noise performance
• 0.65 mΩ primary conductor resistance for low power loss and high inrush current withstand capability
• Small footprint, low-profile SOIC8 package suitable for space-constrained applications
• Integrated shield virtually eliminates capacitive coupling from current conductor to die, greatly suppressing output noise due to high dv/dt transients
• 3 to 3.6 V, single supply operation
• Output voltage proportional to AC or DC current
• Factory-trimmed sensitivity and quiescent output voltage for improved accuracy
• Chopper stabilization results in extremely stable quiescent output voltage
• Nearly zero magnetic hysteresis
• Ratiometric output from supply voltage
