Typical Application

The TP156x in Two-Pole Micro-power Sallen-Key Low-Pass Filter


The TP156x series are CMOS single, dual, and quad RRIO op-amps with low offset, low power and stable high frequency response. They incorporate 3PEAK’s proprietary and patented design techniques to achieve very good AC performance with 3.8MHz bandwidth, 3.6V/μs slew rate and low distortion while drawing only 130μA of quiescent current per amplifier. The input common-mode voltage range extends 300mV beyond V– and V+, and the outputs swing rail-to-rail. The TP156x family can be used as plug-in replacements for many commercially available op-amps to reduce power and improve input/output range and performance. 

The TP156x Op-amps are unity gain stable with any capacitive load. They operate from either single +2.1V to +6.0V supply or dual ±1.05V to ±3.0V supplies. 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. Adaptive biasing and dynamic compensation enables the TP156x to achieve ‘THD +Noise’ for 1kHz/10kHz 2VPP signal at -115dB/ -99dB. Beyond the rails input and rail-to-rail output characteristics allow the full power-supply voltage to be used for signal range. 

The combination of features makes the TP156x ideal choices for audio amplification of computers, sound ports, and other consumer Audio. The TP156x Op-amp is very stable, and it is capable of driving heavy capacitive loads such as those found in LCDs. The ability to swing rail-to-rail at the inputs and outputs enables designers to buffer CMOS DACs, ASICs, or other wide output swing devices in single-supply systems
