TP2114-SR/TP2114-TR 3peak Low Power OPA

The TP2114-SR/TP2114-TR are ultra-low power,precision CMOS op-amps that provide a constant 10kHz bandwidth and 10mV/μs slew rate with only maximum 600nA quiescent current per amplifier.The ground-sensing input common-mode range,guaranteed 1.5mV VOS and ultra-low 0.4μV/°C VOS TC enables accurate and stable measurement for both high side and low side current sensing.

The TP2114-SR/TP2114-TR have carefully designed CMOS input stage that outperforms competitors with typically 0.1fA IB.This ultra-low input current significantly reduces IB and IOS errors introduced in giga-Ωresistance,high impedance photodiode,and charge sense situations.The TP2114-SR/TP2114-TR are unity gain stable with 1,000nF capacitive load.They can operate from a single-supply voltage of+1.8V to+5.5V or a dual-supply voltage of±0.9V to±2.75V,and features ground-sensing inputs and rail-to-rail output.

The combined features make the TP2114-SR/TP2114-TR ideally suited for a variety of 2-cell NiCd/Alkaline battery or single-Li+battery powered portable applications.Potential applications include low frequency signal conditioning,mobile accessories,wireless remote sensing,vibration monitors,ECGs,pulse monitors,glucose meters,smoke and fire detectors,and backup battery sensors.
