MAX4294ESD+

The MAX4294ESD+ is an ultra small, 1.8V, μPower, rail to rail I/O op-amp in 14 pin NSOIC package. This micropower operational amplifier operates from a 1.8V to 5.5V single supply or ±0.9V to ±2.75V dual supplies and has rail to rail input/output capabilities. The combination of low input offset voltage ±200μV and high open-loop gain makes it ideal for low power/low voltage, high precision portable applications. It has an input common mode range that extends to each supply rail and their outputs swing to within 46mV of the rails with a 2Kohm load. Although the minimum operating voltage is specified at 1.8V, this device typically operates down to 1.5V. The combination of ultra-low voltage operation, rail to rail inputs/output and low power consumption makes the device ideal for any portable/two-cell battery-powered system.

• Supply current per amplifier is 100μA
