Medical Equipment
Test Equipment
The small size and low power consumption (120μA
max) of the REF32xx make it ideal for portable and
battery-powered applications. This reference is stable
with any capacitive load.
The REF32xx can be operated from a supply as low
as 5mV above the output voltage, under no load
conditions. All models are specified for the wide
temperature range of –40°C to +125°C.
