INA138NA/3KG4 Typical application Circuitry

INA138NA/3KG4

The INA138NA/3KG4 is a high-side current shunt monitor, epitomizing its capabilities in amplifying a differential voltage signal and projecting this onto a single-ended output. Notably used in applications such as power management systems, battery chargers, and overcurrent protection circuits, the INA138 series, and particularly INA138NA/3KG4, provides a compact, yet robust solution for accurate current sensing.

1. Shunt Voltage Input Terminals:

- IN+ (Pin 3): This pin witnesses the positive side of the shunt resistor, obtaining the high-side voltage of the differential pair.

- IN– (Pin 2): Acquiring the negative side of the shunt resistor, this pin captures the lower potential in the differential configuration.

2. Power Supply and Ground:

- VS (Pin 5): This pin navigates the power supply to the INA138NA/3KG4, where a supply voltage, as per the specifications in the datasheet, ensures operational integrity.

- GND (Pin 4): Serves as the ground reference for the INA138NA/3KG4, ensuring a stable return path for the operative currents.

3. Output Dynamics:

- OUT (Pin 1): Emanating the amplified signal, this pin projects the monitored current (in a voltage form) to be interfaced with subsequent components or systems, such as an ADC (Analog to Digital Converter) or a microcontroller.

4. Gain Set:

- REF (Pin 6): Interacting with an external resistor, this pin fosters the adjustment of the output voltage and, subsequently, the gain of the INA138NA/3KG4, refining the scalability of the output in alignment with application requirements.

5. Shunt Resistor: Selecting an apt shunt resistor is paramount, ensuring accurate current-to-voltage conversion while mitigating excessive power loss across it.

6. Supply Bypass: Including a bypass capacitor close to the VS (Pin 5) and GND (Pin 4) ensures stable operation of the INA138NA/3KG4 by minimizing potential voltage fluctuations.

7. Output Filtering: Implementing a low-pass filter at the output (Pin 1) can subdue potential high-frequency noise, enhancing the measurement accuracy of the INA138NA/3KG4.

Venturing into the realms of current sensing, the INA138NA/3KG4 establishes itself as a proficient component, melding precision and simplicity. An in-depth perusal of the respective datasheet will offer an enriched understanding and additional nuances of the component, aiding designers in crafting meticulous and efficient electronic designs.
