The TP211x series is an ultra-low power, precision CMOS operational amplifier that provides a constant 10-kHz bandwidth and a 10-mV/μs slew rate with a maximum quiescent current of only 600 nA per amplifier. The groundsensing input common-mode range, which guarantees a 1.5-mV VOS and an ultra-low 0.4-μV/°C VOS TC, enables an accurate and stable measurement for both the high-side and low-side current sensing. The TP211x series has a carefully designed CMOS input stage that outperforms competitors with a typically 0.1- fA IB. This ultra-low input current significantly reduces IB and IOS errors introduced in the giga-Ω resistance, high-impedance photodiode, and charge sense situations. The TP211x series is unity gain stable with a 1,000-nF capacitive load. It can operate from a single-supply voltage of +1.8 V to +5.5 V or a dual-supply voltage of ±0.9 V to ±2.75 V, and features ground-sensing inputs and the rail-to-rail output. The combined features make the TP211x series 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.
