GENERAL DESCRIPTION

The MAX74822 is a dual rail-to-rail input and output,

single-supply amplifier featuring very low supply

current and 1MHz bandwidth. All are guaranteed to

operate from a 2.7V single supply as well as a 5V supply.

The MAX74822 provides 1MHz bandwidth at a low

current consumption of 45µA per amplifier.

Very low input bias currents enable the MAX74822 to be

used for integrators, photodiode amplifiers,

piezoelectric sensors, and other applications with high

source impedance. The supply current is only 45μA per

amplifier, ideal for battery operation.

Rail-to-rail inputs and outputs are useful to designers

buffering ASICs in single-supply systems. The MAX74822

is optimized to maintain high gains at lower supply

voltages, which makes it useful for active filters and gain

stages.

The MAX74822 is specified over the extended industrial

temperature range (–40°C to +125°C). The MAX74822

dual is available in an 8-lead MSOP package.
