Description
The DIO2051A is single channel rail-to-rail CMOS
operational amplifier with ultra-low offset.
Features include wide input common-mode
voltage range and broad output voltage swing
with operating supply voltage from 1.8 V to 5.5 V.
Products are fully specified over the extended
-40°C to +125°C temperature range.
The DIO2051A provides a 550 kHz bandwidth,
consuming ultra-low current of 16 μA per channel.
Very low input bias currents of 0.5 pA make the
DIO2051A ideal for integrators, photodiode
amplifiers, and piezoelectric sensors.
