Test Conditions/Comments
Guaranteed monotonic over temperature
Measured at Code 32 in the linear region
At 25°C
T
±1% for specified performance, AVDD = 2xREFIN + 50 mV
Typically 100 MΩ
Typically ±30 nA
Enabled via CR10 in the AD5382 control register;
CR12 selects the reference voltage
At ambient; CR12 = 1; optimized for 2.5 V operation
1.25 V reference selected; CR12 = 0
Temperature Range: +25°C to +85°C
Temperature Range: –40°C to +85°C
