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.
