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.
