Overview
The TP212x are ultra-low power, precision CMOS op-amps featuring a maximum supply current of 950nA per amplifier with an ultra-low typical input bias current of 1pA. Analog trim and calibration routine reduce input offset voltage to below 1.5mV, and the precision temperature compensation technique makes offset voltage temperature drift at 0.5μV/°C, which allowing use of the TP212x in systems with high gain without creating excessively large output offset errors.
The TP212x are unity gain stable with 1,000nF capacitive load with a constant 18kHz GBWP, 10mV/μs slew rate, which make them appropriate for low frequency applications, such as battery current monitoring and sensor conditioning. The TP212x 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 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 due to power supply voltage variations over the lifetime of the battery and maintain high CMRR even for a rail-to-rail input opamp. 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.
