Overview

The INA199 is a zero-drift, bidirectional current-sensing amplifier operating from a 2.7V to 30V single supply, capable of sensing the voltage drop across a shunt resistor at common-mode voltages from -0.2V to 30V. It is primarily used in high-side and low-side current sensing, battery charging, and power management systems. The series offers three fixed gain options: 50V/V, 100V/V, and 200V/V. The zero-drift architecture ensures low offset voltage. Under typical conditions, the INA199 draws 110µA of supply current.

Applications

Configuring the INA199 VREF pin voltage enables unidirectional (positive or negative) and bidirectional (positive and negative) current sensing.
When the REF pin is driven by the negative supply GND voltage, positive current can be sensed within an output voltage range of (50mV ~ V+ - 50mV), with the output voltage increasing linearly as the measured current increases.
When the REF pin is driven by the positive supply V+ voltage, negative current can be sensed within an output voltage range of (50mV ~ V+ - 50mV), with the output voltage decreasing linearly as the measured current increases.
When the REF pin is driven by (VIN+ - GND)/2, both positive and negative currents can be sensed within an output voltage range of (50mV ~ V+ - 50mV)/2. For positive current sensing, the output voltage increases linearly as the measured current increases; for negative current sensing, the output voltage decreases linearly as the measured current increases.
In bidirectional current sensing applications, if the REF pin is driven by an external reference source through a resistor divider, a voltage buffer must be inserted after the divider before driving the REF pin.
In the basic INA199 connections described above, the IN+ and IN- pins should be connected as directly as possible to the sense resistor to minimize any series resistance with the sense resistor. A power supply bypass capacitor is required for stability; a value of 100nF is recommended, placed close to the device's V+ pin.
