TP321-TR/TP321-DF0R Micro Power OPA-3peak

TP321-TR/TP321-DF0R are general purpose single,dual and quad CMOS op-amps with low offset,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 with low cost among all micro-power CMOS amplifiers.

The TP321-TR/TP321-DF0R are 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-TR/TP321-DF0R superior and cost-effective among RRIO CMOS op-amps.The TP321-TR/TP321-DF0R are 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.

The TP321-TR/TP321-DF0R 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.
