Typical Application

The TP154x in Smoke Dectector Applications


TP154x 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 TP154x family can be used as plug-in replacements for many commercially available op-amps to reduce power and improve input/output range and performance. 

TP154x are unity gain stable with Any Capacitive load with a constant 1.3MHz GBWP, 0.9V/μs slew rate while consuming only 37μA of quiescent current per amplifier. Analog trim and calibration routine reduce input offset voltage to below 1.5mV, and proprietary precision temperature compensation technique makes offset voltage temperature drift at 0.6μV/°C. Adaptive biasing and dynamic compensation enables the TP154x to achieve ‘THD+Noise’ for 1kHz/10kHz 2VPP signal at -105dB and -90dB, respectively. 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 TP154x 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. General audio output, remote battery- powered sensors, and smoke detector can benefit from the features of the TP154x op-amps.
