MAX952ESA+

The MAX952ESA+ is an ultra low power, single supply op-amp, comparator and reference in 8 pin NSOIC package. The device operates from single 2.7V to 7V (TA = -10°C to +85°C) supply with typical supply current of 7μA. The inverting input of comparator is connected to an internal 1.2V ±2% bandgap reference. Both op-amp and comparator has common mode input voltage range that extends from negative supply rail to within 1.6V of positive rail. The op-amp in MAX952 is has stability for gains of 10V/V or greater. The op-amp has unique output stage that enables to operate with an ultra low supply current while maintaining linearity under loaded conditions. The comparator output stage of MAX952 continuously sources as much as 40mA and it eliminates power supply glitches that commonly occur when changing logic states by minimizing parasitic feedback and making device the easier to use. It also contains ±3mV internal hysteresis to ensure clean output switching even with slow moving input signals.
