TP2111/TP2111N/TP2112/TP2114  
3PEAK  
Nanopower 300nA, 1.8V, Rail-to-Rail Input/Output Op-amps  
Features  
Description  
The TP211x are ultra-low power, precision CMOS  
op-amps that provide a constant 10kHz bandwidth  
Ultra-low Supply Current:  
300nA Typical / 500nA Maximum per Amplifier  
Stable 10 kHz GBWP with 6 mV/μs Slew Rate  
Offset Voltage: 1.5 mV Maximum  
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 0.4μV/°C VOS TC enables accurate and  
stable measurement for both high side and low side  
current sensing.  
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  
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.  
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  
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.  
Robust 8 kV – HBM and 2 kV – CDM ESD Rating  
Green, Popular Type Package  
Applications  
Current Sensing  
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.  
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
