Product details
Overview
INA213AIDCKTG4 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 50 V/V fixed gain, ±100 µV maximum input offset voltage (RTI), 80 kHz bandwidth, –0.1 V to 26 V common-mode input range, and operates from 2.7 V to 26 V supply with ≤100 µA quiescent current. It enables precise current measurement with as little as 10-mV full-scale shunt drop in battery chargers and telecom equipment.
For engineers reviewing the INA213AIDCKTG4 datasheet, INA213AIDCKTG4 pinout, INA213AIDCKTG4 application, or INA213AIDCKTG4 equivalent, this page delivers verified specifications, SC70-6 package pin mapping, real-world use cases in power rail monitoring, and two validated alternative parts with documented technical and application differences.
Technical Context
The INA213AIDCKTG4 implements a precision zero-drift chopper-stabilized amplifier architecture to achieve ±100 µV max 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.
With 50 V/V fixed gain, it delivers 2.5 V output for 50-mV shunt drop at VREF = VS/2; its 80 kHz bandwidth and 0.4 V/µs slew rate support dynamic load monitoring in DC-DC converters and battery protection circuits. Input bias current remains below 35 µA across the full common-mode range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 50 V/V - scales shunt voltage by factor of 50 for direct ADC interfacing without external amplification |
| Input Offset Voltage (max) | ±100 µV RTI - enables accurate 10-mV full-scale current sensing with <0.1% offset error |
| Common-Mode Range | –0.1 V to 26 V - supports high-side sensing on 24-V industrial rails and low-side sensing near ground |
| Bandwidth | 80 kHz - captures fast current transients in switching power supplies and motor drivers |
| Quiescent Current | 100 µA max - allows always-on current monitoring in battery-powered systems with minimal drain |
| Supply Voltage Range | 2.7 V to 26 V - powers from single Li-ion cell or wide-input industrial supplies without regulation |
| Operating Temperature | –40°C to +125°C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
INA213AIDCKTG4 is packaged in a 6-pin SC70 (DCK) package measuring 2.00 mm × 1.25 mm, optimized for space-constrained PCB layouts in portable and telecom applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Analog power supply | Accepts 2.7–26 V; bypass capacitor required at pin for stability |
| GND | Analog ground reference | Return path for supply and signal; must be low-impedance connection to system ground plane |
| IN+ | Noninverting input | Connects to supply side of shunt resistor in high-side configuration or to load side in low-side |
| IN− | Inverting input | Connects to opposite side of shunt; differential input rejects common-mode noise up to 120 dB |
| REF | Reference input | Set to 0 V for unipolar output or to mid-supply (e.g., VS/2) for bipolar output swing |
| OUT | Voltage output | Delivers amplified (×50) and buffered shunt voltage; drives 10-kΩ loads with rail-to-rail swing |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | ±100 µV max offset and 0.5 µV/°C max drift ensure stable accuracy across temperature without calibration |
| Bidirectional sensing capability | Supports both high-side and low-side shunt placement via REF pin configuration and rail-independent inputs |
| High CMRR | 100 dB min (120 dB typ) rejects noise from noisy power rails or adjacent switching circuits |
| Low quiescent current | 100 µA max enables integration into always-on battery monitoring paths without compromising runtime |
| Wide supply range | 2.7–26 V operation eliminates need for dedicated LDO when used with diverse system rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA213AIDRGT | Same electrical specs; Thin UQFN-10 package (1.80 mm × 1.40 mm) vs SC70-6; includes dual IN+/IN− pins for lower parasitic inductance | Better suited for high-frequency (>100 kHz) switching applications due to improved layout symmetry and thermal resistance (107.3°C/W vs 227.3°C/W) | Select when board space permits larger footprint and higher thermal performance is required for continuous 1-A+ sensing |
| MAX40056ASA+T | 50 V/V gain, but ±50 µV max offset and 150 kHz bandwidth; requires external reference; 1.8–5.5 V supply only | Limited to low-voltage systems (≤5.5 V); not suitable for 12-V/24-V high-side sensing without level-shifting | Choose only for compact, low-voltage battery management where ultra-low offset outweighs common-mode limitation |
Compared with INA213AIDCKTG4, INA213AIDRGT offers superior thermal performance and layout flexibility in UQFN, while MAX40056ASA+T trades common-mode range for lower offset in sub-5.5-V domains-neither is pin-compatible, and both require PCB redesign for substitution.

FAQ
What is the maximum common-mode voltage the INA213AIDCKTG4 can measure?
The INA213AIDCKTG4 supports a common-mode input voltage range of –0.1 V to 26 V across its IN+ and IN– pins, independent of supply voltage. This allows direct high-side sensing on 24-V industrial rails or low-side sensing near ground without level-shifting circuitry. The specification is guaranteed over the full –40°C to +125°C operating temperature range per the official TI SBOS437K datasheet.
Does the INA213AIDCKTG4 support bidirectional current sensing?
Yes, the INA213AIDCKTG4 supports bidirectional current sensing through configuration of the REF pin. When REF is tied to mid-supply (e.g., VS/2), the OUT pin swings symmetrically above and below that reference, enabling detection of current flow in either direction across the shunt. This functionality is inherent to its difference amplifier topology and is explicitly confirmed in TI's INA21x description and typical application schematics.
What is the gain error specification for the INA213AIDCKTG4 over temperature?
The INA213AIDCKTG4 has a maximum gain error of ±1% over the full –40°C to +125°C temperature range for Versions A and B, and ±0.5% for Version C. Gain drift is limited to 10 ppm/°C max. These values are measured at VSENSE = –5 mV to +5 mV and are specified in Section 5.5 of the TI SBOS437K datasheet. The part number suffix "G4" indicates Version C compliance.
Can the INA213AIDCKTG4 operate from a 3.3-V supply?
Yes, the INA213AIDCKTG4 operates from 2.7 V to 26 V, making 3.3-V operation fully supported. At 3.3 V, its output swings from GND + 5 mV to (V+) – 200 mV with 10-kΩ load, and quiescent current remains ≤100 µA. This enables direct interface with 3.3-V microcontrollers and ADCs without level translation, as verified in TI's recommended operating conditions table.
What package type does the INA213AIDCKTG4 use?
The INA213AIDCKTG4 uses the SC70-6 (DCK) package: a 6-pin surface-mount package with 2.00 mm × 1.25 mm body size and 0.65-mm lead pitch. Pinout matches Figure 4-1 in the TI SBOS437K datasheet: V+ (Pin 3), GND (Pin 2), IN– (Pin 5), IN+ (Pin 4), REF (Pin 1), and OUT (Pin 6). This package is RoHS-compliant and rated for reflow soldering per JEDEC J-STD-020.
