Description

The TP321 is general purpose single CMOS op-amps with low offset, high frequency response, low power, low supply voltage, and rail-to-rail inputs and outputs. It incorporates 3PEAK’s proprietary and patented design techniques to achieve best in-class performance with low cost among all micro-power CMOS amplifiers. 


The TP321 is unity gain stable with a constant 1MHz gain-bandwidth product, 1V/μs slew rate while consuming only 45μA of supply current per amplifier. The rail-to-rail input and output characteristics allow the full power-supply voltage to be used for signal range. 


This combination of features makes the TP321 superior and cost-effective among RRIO CMOS op-amps. The TP321 is ideal choices for battery-powered applications because it minimizes 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. 


The TP321 can be used as cost-effective plug-in replacements for many commercially available op amps to reduce power and improve input/output range and performance.
