The ACS724 is provided in a small, low-profile surface-mount

SOIC8 package. The leadframe is plated with 100% matte tin,

which is compatible with standard lead (Pb) free printed circuit

board assembly processes. Internally, the device is Pb-free, except

for flip-chip high-temperature Pb-based solder balls, currently

exempt from RoHS. The device is fully calibrated prior to shipment

from the factory.

Features and Benefits (continued)

• 5 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
