1 / 18 page  3PEAK 1 TP2111/TP2111N/TP2112/TP2114 Nanopower 300nA, 1.8V, Rail-to-Rail Input/Output Op-amps www.3peakic.com REV1.0 Features Ultra-low Supply Current: 300nA Typical / 500nA Maximum per Amplifier Stable 10 kHz GBWP with 6 m V/μs Slew Rate Offset Voltage: 1.5 mV Maximum Ultra-low VOS TC: 0.4 μV/°C Ultra-low Input Bias Current: 0.1 fA Typical Unity Gain Stable for 1,000 nF Capacitive Load High 120 dB Open-Loop Voltage Gain Ground-Sensing Input Common-Mode Range Outputs Swing Rail-to-Rail Outputs Source and Sink 20 mA of Load Current No Phase Reversal for Overdriven Inputs Ultra-low Single-Supply Operation Down to +1.8V Shutdown Current: 3 nA Typical (TP2111N) –40°C to 125°C Operation Range Robust 8 kV – HBM and 2 kV – CDM ESD Rating Green, Popular Type Package Applications Current Sensing Threshold Detectors/Discriminators Low Power Filters Handsets and Mobile Accessories Wireless Remote Sensors, Active RFID Readers Gas/Oxygen/Environment Sensors Battery or Solar Powered Devices Sensor Network Powered by Energy Scavenging Description The TP211x are ultra-low power, precision CMOS op-amps that provide a constant 10kHz bandwidth and 10mV/ μs slew rate with only 300nA quiescent current per amplifier. The ground-sensing input common-mode range, guaranteed 1.5mV VOS and ultra-low 0.4 μV/°C V OS TC enables accurate and stable measurement for both high side and low side current sensing. The TP211x have carefully designed CMOS input stage that outperforms competitors with typically 0.1fA IB. This ultra-low input current significantly reduces IB and IOS errors introduced in giga-Ω resistance, high impedance photodiode, and charge sense situations. The TP211x are unity gain stable with 1,000nF capacitive load. They can operate from a single -supply voltage of +1.8V to +6.0V or a dual-supply voltage of ±0.9V to ±3.0V, and features ground-sensing inputs and rail-to-rail output. The combined features make the TP211x ideally suited for a variety of 2-cell NiCd/Alkaline battery or single-Li+ battery powered portable applications. Potential applications include low frequency signal conditioning, mobile accessories, wireless remote sensing, vibration monitors, ECGs, pulse monitors, glucose meters, smoke and fire detectors, and backup battery sensors. For applications that require power-down, the TP2111N has a low-power shutdown mode that reduces supply current to 3nA typically, and forces the output into a high-impedance state. 3PEAK and the 3PEAK logo are registered trademarks of 3PEAK INCORPORATED.
