The device is a specially-designed, current-sensing amplifier that can accurately measure voltages developed across a current-sensing resistor. The device is capable of measuring current on input voltage rails as high as 26 V and as low as 2.7 V. The zero-drift topology enables high-precision measurements with maximum input offset voltages as low as 170 µV with a maximum temperature contribution of 0.5 µV/°C over the full temperature range of –40 °C to +125 °C. 8.2 Functional Block Diagram The simplified functional diagram below shows the device power is provided by the voltage on the IN+ pin. This diagram also shows the nominal values for the internal gain set resistors. The nominal value of these resistors can vary by 20% or more; however, the matching between these resistors is tightly controlled. The matching of these internal resistors results in a precise fixed gain that varies very little over temperature.

Instead, an internal connection to the IN+ pin serves as the power supply for this device. This allows the device to be used in applications where lower voltage or sub-regulated supply rails are not present. The operational voltage range on this pin is 2.7 V to 26 V and is designed for power-supply applications. The maximum current drawn from the IN+ pin is 130 μA, when the current sense voltage is zero. 8.3.2 Low Gain Error and Offset Voltage The maximum gain error of the INA183 is 0.4% and is specified over the full operational temperature range. The low gain error allows for accurate measurements as the sense voltage increases, and is designed for applications that need to detect overcurrent conditions accurately. The offset voltage of the INA183 is specified to be ±170 μV for all gain options. The low offset voltage allows for increased accuracy when the sense voltage is small or allows for reduction in the size of the current sense resistor with less impact on the total measurement accuracy. Smaller value resistors reduce the power loss in the application which allows the use of lower wattage resistors that are generally lower cost. 8.3.3 Low Drift Architecture The INA183 features low drift for both the gain error and offset voltage specifications. The low gain error drift of 10 PPM/ºC results from the well matched internal resistor network that sets the device gain. The low offset drift 10 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: INA183 INA183 www.ti.com SBOSA08 – FEBRUARY 2021 is due to the internal chopping architecture of the amplifier. Input chopping reduces both the offset and offset drift since any change in offset is canceled with each chopping cycle. The maximum input offset drift of the INA183 is 0.5 μV/ºC. The low drift of the gain error and offset voltage provides accurate current measurement over the operational temperature range of -40ºC to 125ºC that exceeds the performance of most discrete current sensing implementations. 8.4 Device Functional Modes 8.4.1 Normal Operation The INA183 is in normal operation when the following conditions are met: • • • The voltage at the IN+ pin is between 2.7 V and 26 V. The maximum differential input signal times the gain is less than VIN+ minus the output voltage swing to VIN+. The minimum differential input signal times the gain is greater than the swing to GND. During normal operation, this device produces an output voltage that is the amplified representation of the difference voltage from IN+ to IN–. 8.4.2 Unidirectional, High-Side Operation The INA183 measures the differential voltage developed by current flowing through a resistor that is commonly referred to as a current shunt resistor or current-sensing resistor. The INA183 operates in high-side, unidirectional mode only, meaning it only senses current sourced from a power supply to a system load as shown in Figure 8-1. 12-V Supply R2 ISENSE IN+ R1 + RSENSE R1 IN± Internal Amplifier OUT ± R2 Load GND Figure 8-1. High-Side Unidirectional Application 8.4.3 Input Differential Overload If the differential input voltage (VIN+ – VIN–) times gain exceeds the voltage swing specification, the INA183 drives the output as close as possible to the IN+ pin or ground, and does not provide accurate measurement of the differential input voltage. If this input overload occurs during normal circuit operation, then reduce the value of the shunt resistor or use a lower-gain version with the chosen sense resistor to avoid this mode of operation. If a differential overload occurs in a fault event, then the output of the INA183 returns to the expected value approximately 30 µs after removal of the fault condition. When the input differential voltage is overloaded the bias currents will increase by a significant amount. The increase in bias currents will occur even with the device is powered down. Input differential overloads less than the absolute maximum voltage rating do not damage the device or result in an output inversion.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. 9.1 Application Information The INA183 measures the voltage developed across a current-sensing resistor when current passes through it. The ability to drive the reference pin to adjust the functionality of the output signal offers multiple configurations, as discussed throughout this section. 9.1.1 RSENSE and Device Gain Selection Choosing the largest possible shunt resistor will maximize the accuracy of any current-sense amplifier. A large sense resistor maximizes the differential input signal for a given amount of current flow and reduces the error contribution of the offset voltage. However, there are practical limits as to how large the current-sense resistor can be in a given application because of the resistor size and maximum allowable power dissipation. Equation 1 gives the maximum value for the current-sense resistor for a given power dissipation budget: RSENSE PDMAX IMAX2 (1) where: • • PDMAX is the maximum allowable power dissipation in RSENSE. IMAX is the maximum current expected to flow through RSENSE. An additional limitation on the size of the current-sense resistor and device gain is due to the power-supply voltage at the IN+ pin, and device swing-to-rail limitations. To ensure that the current-sense signal is properly passed to the output, both positive and negative output swing limitations must be examined. Equation 2 provides the maximum values of RSENSE and GAIN to keep the device from exceeding the positive swing limitation. IMAX ª RSENSE ª *$,1 < VSP (2) where: • • • IMAX is the maximum current that will flow through RSENSE. GAIN is the gain of the current-sense amplifier. VSP is the positive output swing as specified in the data sheet. Positive output swing limitations should be considered when selecting the value of RSENSE. There is always a trade-off between the value of the sense resistor and the gain of the device under consideration. If the sense resistor selected for the maximum power dissipation is too large, then it is possible to select a lower-gain device to avoid positive swing limitations. 12 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: INA183 INA183 www.ti.com SBOSA08 – FEBRUARY 2021 The negative swing specification limits how small the sense resistor value can be for a given application. Equation 3 provides the limit on the minimum value of the sense resistor. IMIN ª RSENSE ª *$,1 > VSN (3) where: • • • IMIN is the minimum current that will flow through RSENSE. GAIN is the gain of the current-sense amplifier. VSN is the negative output swing of the device. 9.2 Typical Application Figure 9-1 shows the basic connections for the INA183. The input pins, IN+ and IN–, must be connected as close as possible to the shunt resistor to minimize any resistance in series with the shunt resistor. RSENSE CBYP 12V Server Power Supply 0.1 …F IN+ IN- INA183 Server 12-V Subsystem OUT GND Figure 9-1. Typical Server Application A power-supply bypass capacitor is required on the IN+ pin. Applications with noisy or high-impedance power supplies may require additional decoupling capacitors to reject power-supply noise. Connect bypass capacitors close to the device pins. In server applications, the INA183 typically monitors the current on the 12-V bus that is distributed to various server sub-systems like memory, storage, or CPU power. The monitored current can be used by the server for fault detection or sub-system power optimization. 9.2.1 Design Requirements Table 9-1 lists the design setup for this application. Table 9-1. Design Parameters DESIGN PARAMETERS EXAMPLE VALUE High-side supply voltage (VIN+) 12 V Maximum sense current (IMAX) 5A Gain option 50 V/V 9.2.2 Detailed Design Procedure The maximum value of the current-sense resistor is calculated based on choice of gain, the value of the maximum current the be sensed (IMAX), and the power-supply voltage (VIN+). When operating at the maximum current, the output voltage must not exceed the positive output swing specification, VSP. Under the given design parameters, Equation 4 calculates the maximum value for RSENSE as 47.2 mΩ. RSENSE < VSP IMAX u GAIN (4) Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: INA183 13 INA183 www.ti.com SBOSA08 – FEBRUARY 2021 For this design example, a value of 40.2 mΩ is selected because, while the 40.2 mΩ is less than the maximum value calculated, 40.2 mΩ is still large enough to give an adequate signal at the current-sense amplifier output. To reduce resistor power losses or to operate over a reduced output range, smaller value resistors can be used as the expense of dynamic range and low current accuracy. 9.2.3 Application Curve Figure 9-2 shows the output response of the device to a sinusoidal current.

INA183 Output Response 14 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: INA183 INA183 www.ti.com SBOSA08 – FEBRUARY 2021 10 Power Supply Recommendations The device is powered from the IN+ pin with a voltage from 2.7 V to 26 V. The voltage at the output will also be limited by this voltage during overload or fault conditions. Also, the INA183 can withstand the full input signal range up to 26 V on the IN– pin, regardless of whether the device has power applied or not. 11 Layout 11.1 Layout Guidelines • • Connect the input pins to the sensing resistor using a kelvin or 4-wire connection. This connection technique ensures that only the current-sensing resistor impedance is detected between the input pins. Poor routing of the current-sensing resistor commonly results in additional resistance present between the input pins. Given the very low ohmic value of the current resistor, any additional high-current carrying impedance can cause significant measurement errors. Place the power-supply bypass capacitor as close as possible to the IN+ pin and ground pins. TI recommends using a bypass capacitor with a value of 0.1 μF. Additional decoupling capacitance can be added to compensate for noisy or high-impedance power supplies. 11.2 Layout Example Direction of Current Flow RSHUNT Bus Voltage: 2.7 V to 26 V LOAD CBYPASS VIA to Ground Plane Current Sense Output GND GND OUT IN+ IN- Figure 11-1.
