The TP211x in Low Side Battery Current Sensor
产品概述
典型应用
The TP2111 is ultra-low power, precision CMOS op-amp that provides a constant 10kHz bandwidth and
10mV/μs slew rate with only 300nA 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 TP2111 has 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 TP2111 is unity gain stable with 1,000nF capacitive
load. They can operate from a single -supply voltage of +1.8V to +6.0V or a dual-supply voltage of ±0.9V to
±3.0V, and features ground-sensing inputs and rail-to-rail output.
The combined features make the TP2111 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.
