ACS709
Features and Benefits
▪ Industry-leading noise performance with 120 kHz
bandwidth through proprietary amplifier and filter
design techniques
▪ Integrated shield greatly reduces capacitive coupling
from current conductor to die due to high dV/dt, and
prevents offset drift in high-side applications
▪ Small footprint surface mount QSOP24 package
▪ 2100 VRMS isolation voltage between primary current
path and sensor IC electronics
▪ 1.1 mΩ primary conductor resistance for low power loss
▪ User-settable Overcurrent Fault level
▪ Overcurrent Fault signal typically responds to an
overcurrent condition in < 2 μs
▪ Filter pin capacitor sets analog signal bandwidth
▪ ±2% typical output error
▪ 3 to 5.5 V, single supply operation
▪ Factory trimmed sensitivity, quiescent output voltage,
and associated temperature coefficients
▪ Chopper stabilization results in extremely stable
quiescent output voltage
▪ Ratiometric output from supply voltage
