Test Conditions/Comments
Guaranteed monotonic over temperature
Measured at Code 256 in the linear region
At 25°C
T
±1% for specified performance
Typically 100 MΩ
Typically ±30 nA
Enabled via CR10 in the AD5382 control register,
CR12 selects the reference voltage
At ambient; CR12 = 0; optimized for 1.25 V operation
2.5 V reference selected; CR12 = 1
Temperature Range: +25°C to +85°C
Temperature Range: –40°C to +85°C
DVDD = 2.7 V to 3.6 V
Total for all pins, T
SMBus-compatible at DVDD < 3.6 V
SMBus-compatible at DVDD < 3.6 V
Input filtering suppresses noise spikes of less than 50 ns
