TP151x series are CMOS single/dual/quad op-amps with low offset, stable high frequency response, low power, low supply voltage, and rail-to-rail inputs and outputs. They incorporate 3PEAK’s proprietary and patented design techniques to achieve best in-class performance among all micro-power CMOS amplifiers in its power class. The TP151x family can be used as plug-in replacements for many commercially available op-amps to reduce power and improve input/output range and performance.

TP151x are unity gain stable with Any Capacitive load with a constant 150kHz GBWP, 0.09V/μs slew rate while consuming only 4μA of quiescent current per amplifier. Analog trim and calibration routine reduce input offset voltage to below 3.0mV, and proprietary precision temperature compensation technique makes offset voltage temperature drift at 0.6μV/°C. Beyond the rails input and rail-to-rail output characteristics allow the full power-supply voltage to be used for signal range. This combination of features makes the TP151x OPA 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 op-amp. Battery Current Monitor, consumer devices, handheld instrumentation, Remote battery-powered sensors, hazard detection (for example, smoke, fire, and gas), and patient monitors can benefit from the features of the TP151x op-amps. For applications that require power-down, the TP1511N in popular type packages has a low-power shutdown mode that reduces supply current to less than 0.1μA, and forces the output into a high-impedance state.
