Features:
1. Extremely low static power consumption
The static current Iq can be as low as nA level, and the sleep mode can be below 1nA.
A single button battery can support several years of operation.
2. Wide/low power supply voltage
Commonly used 1.2V~5.5V single power supply, some support * * ± 0.6V~± 2.75V * * dual power supply.
Suitable for low voltage scenarios such as batteries and energy harvesting.
3. Rail to Rail (RRIO)
The input/output voltage range is close to the power rail, making full use of the dynamic range at low voltages.
4. High precision and low noise (high-end models)
Chopping stable zero/zero drift: offset voltage * *<1 μ V * *, temperature drift * *<0.01 μ V/℃ * *.
Low input bias current (pA level), low noise.
5. Miniaturization packaging
SOT-23-5, SC70, DFN, WSON, etc. are suitable for portable/high-density PCBs.
6. Turn off/enable function
During sleep, the current drops sharply and quickly wakes up in microseconds.
Applications：
1. Portable/Wearable Devices
Smart watches, wristbands, TWS earphones, hearing aids: sensor signal amplification, battery monitoring, audio front-end.
2. Medical Electronics
Dynamic electrocardiogram (ECG), blood glucose monitoring, oximeter: weak physiological signal amplification, low noise, high precision.
3. Internet of Things (IoT) sensor nodes
Wireless temperature and humidity, gas, pressure, and soil sensors: powered by long-term batteries/energy harvesting.
4. Industry and Measurement
4-20mA current loop, intelligent transmitter, data acquisition (DAQ), high-precision instrument.
Battery Management System (BMS), onboard sensors, low-power control module.
