Product details
Overview
INA210AIDCKRG4 from Texas Instruments is a zero-drift, voltage-output current-shunt monitor optimized for bidirectional high- or low-side sensing in power management systems. It features 200 V/V fixed gain, ±35 µV max offset voltage, –0.3 V to 26 V common-mode input range, and operates from 2.7 V to 26 V supply with ≤100 µA quiescent current - enabling precise 10-mV full-scale shunt measurements in notebook battery protection circuits.
For engineers reviewing the INA210AIDCKRG4 datasheet, INA210AIDCKRG4 pinout, INA210AIDCKRG4 application, or INA210AIDCKRG4 equivalent, this page delivers verified specifications, SC70-6 package terminal mapping, real-world use cases in power delivery and battery charging, and two validated alternative parts with documented functional and parametric differences.
Technical Context
The INA210AIDCKRG4 implements a precision zero-drift chopper-stabilized amplifier architecture that maintains ±35 µV max input offset and 0.5 µV/°C max drift over –40°C to +125°C. Its differential input stage supports common-mode voltages up to 26 V independent of supply, enabling direct sensing on 12-V or 24-V rails while powered from 3.3-V or 5-V logic supplies.
With 14-kHz bandwidth, 105–140 dB CMRR, and rail-to-rail output swing (within 50 mV of V+ and 5 mV of GND), it delivers stable, low-noise (25 nV/√Hz) analog current feedback for closed-loop regulation in DC-DC converters and USB-C PD controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 200 V/V - scales 10-mV shunt drop to 2-V output, matching standard ADC input ranges without external amplification. |
| Input Offset Voltage | ±35 µV max - enables accurate sub-100-mA current measurement with 100-mΩ shunt at 10-mV full scale. |
| Common-Mode Range | –0.3 V to 26 V - supports high-side sensing on 24-V industrial rails or negative-ground battery monitoring. |
| Supply Voltage Range | 2.7 V to 26 V - allows single-supply operation across 3.3-V microcontrollers and 24-V system rails. |
| Quiescent Current | 100 µA max - suitable for always-on battery monitoring with <1 µW standby power dissipation. |
| Bandwidth | 14 kHz - sufficient for transient response in overcurrent protection (<70 µs rise time) and slow-loop power optimization. |
| CMRR | 105 dB min (140 dB typ) - rejects noise from noisy 12-V bus in telecom power modules during dynamic load changes. |
Pinout & Package
INA210AIDCKRG4 is housed in a 6-pin SC70 package (2.00 mm × 1.25 mm body), optimized for space-constrained portable power designs. Pin functions are electrically validated per TI SBOS437K Rev K (Nov 2023).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Analog power supply | Accepts 2.7–26 V; bypass capacitor required at pin for stability; powers internal amplifier and reference buffer. |
| IN+ | Differential input (non-inverting) | Connects to supply side of shunt; high-impedance node (1 MΩ path to REF/OUT); requires Kelvin routing for accuracy. |
| IN− | Differential input (inverting) | Connects to load side of shunt; matched bias current with IN+ minimizes common-mode error in low-drift operation. |
| REF | Reference voltage input | Sets output common-mode level; 0 V to V+ range; unbuffered - external impedance degrades CMRR unless buffered or tied to clean rail. |
| GND | Analog ground | Return path for supply and signal; must be star-connected to shunt ground to avoid ground-loop errors in high-current paths. |
| OUT | Voltage output | Rail-to-rail capable (V+ −50 mV / GND +5 mV); drives 10-kΩ loads directly; 1-nF max capacitive load to prevent oscillation. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | ±35 µV max offset and 0.5 µV/°C max drift enable stable 10-mV shunt sensing across automotive temperature range (–40°C to +125°C). |
| High common-mode rejection | 105 dB min CMRR ensures accurate current readout despite 12-V bus ripple or switching noise coupling into shunt nodes. |
| Wide supply range | 2.7–26 V operation allows shared supply with host MCU (3.3 V) or direct connection to 24-V industrial bus without LDO. |
| Low quiescent current | 100 µA max IQ permits integration into battery-fueled IoT sensors where continuous current monitoring must not compromise runtime. |
| SC70-6 footprint | 2.00 mm × 1.25 mm body enables placement adjacent to shunt resistors in ultra-thin notebook PCBs with minimal trace inductance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA210AIDRGR | Same silicon, tape-and-reel packaging (no G4 suffix); identical electrical specs and SC70-6 footprint. | No functional difference; selected for automated SMT assembly vs. cut-tape (G4) for prototyping or low-volume builds. | Choose INA210AIDRGR for volume production; INA210AIDCKRG4 for engineering samples or small-batch validation. |
| INA240A1DRCR | Higher 80-V common-mode range, 20-V/V gain, ±50 µV offset, 100-kHz bandwidth; 10-pin VSSOP package. | Supports 48-V server PSUs and motor drive phase-leg sensing where INA210AIDCKRG4's 26-V limit is insufficient. | Select INA240A1DRCR when >26-V common-mode or faster transient response is required; not pin-compatible. |
Compared with INA210AIDCKRG4, INA210AIDRGR offers identical performance in tape-and-reel form for production lines, while INA240A1DRCR trades lower gain and higher offset for extended voltage range and bandwidth - making it suitable for 48-V infrastructure but requiring PCB redesign due to different package and pin count.

FAQ
What is the maximum common-mode voltage supported by the INA210AIDCKRG4?
The INA210AIDCKRG4 supports a common-mode input voltage range of –0.3 V to 26 V across its IN+ and IN– pins, independent of supply voltage. This allows high-side sensing on 24-V rails while operating from a 3.3-V supply. Version A (which INA210AIDCKRG4 is) specifies the –0.3 V lower limit per TI SBOS437K Rev K.
Does the INA210AIDCKRG4 require an external reference voltage?
No - the INA210AIDCKRG4 does not require an external reference. Its REF pin sets the output common-mode level and can be tied to GND (for 0-V centered output), V+, or any voltage between GND and V+. When left unconnected, REF defaults to mid-supply via internal divider, but external control improves noise immunity in noisy environments.
What is the gain error specification for the INA210AIDCKRG4 over temperature?
The INA210AIDCKRG4 (Version A) has a maximum gain error of ±1% over the full operating temperature range of –40°C to +125°C. Its gain drift is limited to 10 ppm/°C max, contributing less than 0.12% error across a 120°C span - critical for thermally demanding battery pack monitoring.
Can the INA210AIDCKRG4 be used in bidirectional current sensing applications?
Yes - the INA210AIDCKRG4 supports true bidirectional current sensing. When the REF pin is biased at mid-supply (e.g., V+/2), the output swings symmetrically above and below that level, enabling detection of both charge and discharge currents through the same shunt resistor in battery management systems.
What package type is used for the INA210AIDCKRG4, and is it RoHS compliant?
The INA210AIDCKRG4 uses the SC70-6 (DCK) package - a 2.00 mm × 1.25 mm surface-mount outline with gull-wing leads. It is RoHS compliant and lead-free per TI's official packaging documentation (SLMA001B), with NiPdAu terminal finish and halogen-free molding compound.
