Test Conditions/Comments
Buffered mode
Unbuffered mode
Minimum Differential voltage
between VREF+ and VREF- pins
is 400mV
Buffered mode
Unbuffered mode
Available from each current
source – 10/50/200uA nominal
Iout >= 50uA
Using internal reference resistor
Using external 150 kΩ reference
resistor between IREF pin and
AGND. Resistor must have a drift
spec of 5ppm/°C
Matching between both current
sources
