Current monitoring accuracy:

– Offset voltage: ±5 µV (maximum)

– Offset drift: ±0.02 µV/°C (maximum)

– Gain error: ±0.1% (maximum)

– Gain error drift: ±25 ppm/°C (maximum)

– Common mode rejection: 140 dB (minimum)

Power monitoring accuracy: 0.7% full scale, –40°C to +125°C (maximum)

Fast alert response: 75 μs

Wide common-mode range: –0.3 V to +85 V

Bus voltage sense input: 0 V to 85 V

Shunt full-scale differential range: ±163.84 mV / ±40.96 mV

Input bias current: 2.5 nA (maximum)

Temperature sensor: ±1°C (maximum at 25°C)

Programmable conversion time and averaging

2.94-MHz high-speed I2C interface with 16 pinselectable addresses
