概述
The TP2191 is a precision, ultra-low power CMOS op-amp featuring a maximum supply current of 900 nA with an ultra-low typical input bias current of 1 pA. The precision temperature compensation technique makes offset voltage temperature drift at 0.4 μV/°C, which allowing use of the TP2191 in systems with high gain without creating excessively large output offset errors.
The TP2191 is unity gain stable with a constant 18 kHz GBWP, 10 mV/μs slew rate, which make them appropriate for low frequency applications, such as battery current monitoring and sensor conditioning. The TP2191 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 makes it very prominent in low voltage (< 3V) rail-to-rail input applications.
The combined features make the TP2191 an ideal choice for battery-powered applications because it minimizes errors due to power supply voltage variations over the lifetime of the battery and maintain high CMRR even for a rail-to-rail input op-amp. 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 TP2191 op-amp.
