Descriptions
The DIO2352X is an ultra-low offset voltage rail-to-
rail input and output voltage feedback amplifier.
They have a wide input common-mode voltage
range and output voltage swing, and take the
operating supply voltage is from 2.5 to 5.5V.
The DIO2352X features an offset voltage of only
30μV and drift of 0.01μV/° which makes the
C,
product perfect in applications of intolerant errors.
Temperature/position/pressure
sensors
and
medical equipment can benefit greatly from nearly
zero drift over their operating temperature range.
