Descriptions
The DIO20321 (single), DIO20322 (dual), DIO20324
(quad), and DIO2036 (sextuple) are amplifiers with
very low noise, low voltage, and low power. The
DIO2032X has a high gain-bandwidth product of 6
MHz, a slew rate of 3.6 V/μs, and a quiescent
current of 385 μA/amplifier typically at 5 V.
The DIO2032X is designed to provide optimal
performance in low-voltage and low-noise
systems. All these chips provide rail-to-rail output
swing for heavy loads. The input common-mode
voltage range includes ground, and the maximum
input offset voltage is 3.5 mV for DIO2032X.
