Typically ±30 nA
Enabled via CR8 in the AD5383 control register,
CR10 selects the reference voltage
At ambient; optimized for 2.5 V operation; CR10 = 1
1.25 V reference selected; CR10 = 0
Temperature range: 25°C to 85°C
Temperature range: −40°C to +85°C
DVDD = 2.7 V to 5.5 V
Total for all pins; TA = TMIN to TMAX
