DIO235X
12μV Vos, 1.2MHz, RRIO CMOS High-Precision Amplifier
Descriptions
Features
The DIO235X 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.
They provide 1.2MHz bandwidth.
Rail-to-Rail Input and Output
Low offset (VOS): 12μV typ.
Input offset drift: 0.01μV/°C
Unity Gain Stable
Gain Bandwidth Product: 1.2MHz
Very low input bias currents: 20pA
Wide supply range: 2.5V to 5.5V
Single Supply Operation
The DIO235X features an offset voltage of only
12μV and drift of 0.01μV/°C, which makes the
product perfect in applications of intolerant errors.
Low power: 0.73mA per channel
