DIO85571

350 μA, 6 MHz, Rail-to-Rail I/O CMOS Operational

Amplifier

Description

The DIO85571 is an amplifier with very low noise, low voltage, and low power operational. The DIO85571 has

a high gain-bandwidth product of 6 MHz, a slew rate of 3.6 V/μs, and a quiescent current of 350 μA/amplifier

at 5 V typically.

The DIO85571 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 3.5 mV for the DIO85571.

They are specified over the extended industrial temperature range (-40°C to +125°C). The operating range is

from 2.5 V to 5.5 V.
