TP2111-TR/TP2111-CR 600nA,5V OP-AMPS-思瑞浦

The TP2111-TR/TP2111-CR are ultra-low power,precision CMOS op-amps featuring a maximum supply current of 950nA per amplifier with an ultra-low typical input bias current of 1fA.Analog trim and calibration routine reduce input offset voltage to below 1.5mV,and the precision temperature compensation technique makes offset voltage temperature drift at 0.5μV/°C,which allowing use of the TP2111-TR/TP2111-CR in systems with high gain without creating excessively large output offset errors.

The TP2111-TR/TP2111-CR are unity gain stable with 1,000nF capacitive load with a constant 18kHz GBWP,10mV/μs slew rate,which make them appropriate for low frequency applications,such as battery current monitoring and sensor conditioning.The TP212x can operate from a single-supply voltage of+1.8V to+6.0V or a dual-supply voltage of±0.9V to±3.0V.Beyond the rails input and rail-to-rail output characteristics allow the full power-supply voltage to be used for signal range.

The combined features make the TP2111-TR/TP2111-CR ideal choices for battery-powered applications because they minimize errors due to power supply voltage variations over the lifetime of the battery and maintain high CMRR even for a rail-to-rail input opamp.Mobile accessories,wireless remote sensing,backup battery sensors,and single-Li+or 2-cell NiCd/Alkaline battery powered systems can benefit from the features of the TP2111-TR/TP2111-CR op-amps.
