5V, CMOS, Rail-to-Rail, General-Purpose Amplifiers

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.
