TP1514-SR/TP1514-TR Micro Power OPA-3PEAK

The TP1514-SR/TP1514-TR family includes CMOS single/dual/quad op-amps with low offset,stable high-frequency response,low power,low supply voltage,and rail-torail inputs and outputs.This family incorporates 3PEAK’s proprietary and patented design techniques to achieve the best-in-class performance among all micro-power CMOS amplifiers in its power class.

The TP1514-SR/TP1514-TR family can be used as plug-in replacements for many commercially available op-amps to reduce power and improve input/output range and performance.TP1514-SR/TP1514-TR family is unity-gain stable with any capacitive load with a constant 150 kHz GBWP,0.09 V/μs slew rate while consuming only 4μA of quiescent current per amplifier.Analog trim and calibration routine reduce input offset voltage to below 3.0 mV,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 TP1514-SR/TP1514-TR OPA an ideal choice for battery-powered applications because the TP1514-SR/TP1514-TR family minimizes errors due to power supply voltage variations over the lifetime of the battery and maintains high CMRR even for a railto-rail input op-amp.Battery current monitors,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 TP1514-SR/TP1514-TR op-amps.
