概述
The TP212x is a series of ultra-low-power, precision CMOS op amps featuring a maximum supply current of 950 nA per amplifier with an ultra-low typical input bias current of 1 pA. Analog trim and calibration routine reduce the input offset voltage to below 1.5 mV, and the precision temperature compensation technique makes offset voltage temperature drift at 0.5 μV/°C, which allows the use of the TP212x in systems with high gain without creating excessively large output offset errors.
The TP212x series is unity-gain stable with 1,000-nF capacitive load with a constant 18-kHz GBWP, 10-mV/μs slew rate, which makes it suitable for low-frequency applications, such as battery current monitoring and sensor conditioning. The TP212x operates from a singlesupply voltage from 1.8 V to 6.0 V or a dual-supply voltage from ±0.9 V to ±3.0 V. Beyond the rails input and rail-to-rail output characteristics allow the full power-supply voltage to be used for signal range.
The combined features make the TP212x ideal choices for battery-powered applications because they minimize errors caused by 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 TP212x op amps.
