The DIO2031/2/3/4/6 is designed to provide
optimal performance in low voltage and low noise
systems. All these chips provide rail-to-rail output
swing into heavy loads. The input common-mode
voltage range includes ground, and the maximum
input offset voltage is 3.5mV for DIO2031/2/3/4/6.
The DIO2033 has a power-down disable feature
that
reduces
the
supply
current
to
90nA
individually.
They are specified over the extended industrial
temperature range (-40
℃
to +125
℃
). The
operating range is from 2.5V to 5.5V.
Descriptions
The DIO2031 (single), DIO2032 (dual), DIO2033
(single with shutdown), DIO2034 (quad) and
DIO2036 (Triple) are amplifiers with very low noise,
low voltage, and low power operational. The
DIO2031/2/3/4/6
quiescent
typically.
has
of
a
high
gain-bandwidth

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Rating” may cause permanent damage to the device. These are stress
ratings only and functional operation of the device at these or any other condition beyond those indicated in the operational sections
of the specifications is not implied. Exposure to absolute maxim rating conditions for extended periods may affect device reliability.
