Product details
Overview
INA210AIDCKT 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 maximum offset voltage, –0.3 V to 26 V common-mode input range, and operates from 2.7 V to 26 V supply. It enables precision 10-mV full-scale shunt measurements in battery chargers and telecom power rails.
For engineers reviewing the INA210AIDCKT datasheet, INA210AIDCKT pinout, INA210AIDCKT application, or INA210AIDCKT equivalent, this page delivers verified specifications, SC70 package layout, real-world use cases, and validated alternative parts - all grounded in TI's SBOS437K production data sheet.
Technical Context
The INA210AIDCKT implements a zero-drift chopper-stabilized amplifier architecture with matched internal resistor networks (R3 = R4 = 5 kΩ), enabling ultra-low offset drift of 0.5 µV/°C and 10 ppm/°C gain drift over –40°C to +125°C. Its differential input stage rejects common-mode voltages up to 26 V independent of supply voltage.
It uses a single-ended output stage referenced to an externally supplied REF pin (0 V to V+), supporting ratiometric or absolute output configurations. Input bias currents remain below 35 µA across its full common-mode range, and it achieves 14 kHz bandwidth with 0.4 V/µs slew rate into 10-kΩ loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | Fixed 200 V/V - sets output = 200 × (VIN+ – VIN–) + VREF, enabling 10-mV shunt drop to produce 2-V output swing |
| Offset Voltage (max) | ±35 µV - allows accurate measurement of sub-100-mA currents with 100-mΩ shunt at 10-mV full scale |
| Common-Mode Range | –0.3 V to 26 V - supports direct sensing on 24-V industrial rails or negative-bias circuits without level shifting |
| Supply Voltage Range | 2.7 V to 26 V - powers from single Li-ion cell up to 24-V system rail; no external regulator needed |
| Quiescent Current (max) | 100 µA - enables always-on current monitoring in battery-backed systems with <1 µW standby dissipation |
| Bandwidth | 14 kHz - sufficient for DC–10 kHz load transient detection in DC-DC converters and battery protection ICs |
| CMRR (min) | 105 dB - suppresses 26-V common-mode noise to <10 µV RTI error, critical for noisy motor drive or SMPS environments |
Pinout & Package
INA210AIDCKT is packaged in a 6-pin SC70 (DCK) footprint measuring 2.00 mm × 1.25 mm, optimized for space-constrained PCB layouts in portable and telecom equipment. The package supports reflow soldering per JEDEC J-STD-020 and has a thermal resistance of 227.3°C/W (junction-to-ambient).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (REF) | Analog input | Reference voltage input (0 V to V+); sets output common-mode level; must be buffered if sourced from resistive divider |
| 2 (IN–) | Analog input | Inverting input; connects to load side of shunt; 5-kΩ internal resistor to GND defines CMRR performance |
| 3 (V+) | Analog power supply | Positive supply rail (2.7 V–26 V); requires 0.1-µF ceramic bypass capacitor placed ≤2 mm from pin |
| 4 (IN+) | Analog input | Non-inverting input; connects to supply side of shunt; matched 5-kΩ internal resistor ensures gain accuracy |
| 5 (GND) | Analog ground | Device ground reference; must tie to low-impedance system ground plane near shunt to minimize noise coupling |
| 6 (OUT) | Analog output | Voltage-output stage; drives 10-kΩ min load; swing limited to (V+) – 0.2 V and GND + 5 mV over temperature |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Enables stable 10-mV full-scale shunt sensing with <0.5 µV/°C offset drift - eliminates calibration over temperature |
| High common-mode rejection | 105 dB minimum CMRR ensures <10 µV error from 26-V common-mode transients - critical for high-side sensing in SMPS |
| Low quiescent current | 100 µA max draw allows continuous current monitoring in energy-harvesting or coin-cell-powered systems |
| Wide supply range | 2.7 V–26 V operation supports single-supply designs across battery, USB, and industrial 24-V rails without LDO |
| SC70 package | 2.0 mm × 1.25 mm footprint saves >60% board area vs SOIC-8 - ideal for compact notebook and 5G baseband modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA214AIDCKT | 100 V/V gain, ±60 µV max offset, same SC70 package and supply range | Better suited for higher-shunt-drop applications (e.g., 20-mV full scale); lower gain reduces noise gain but requires larger shunt for same output swing | Select when system design uses ≥20-mΩ shunts and prioritizes lower output noise over minimal shunt dissipation |
| MAX4080TASA+ | 200 V/V gain, ±200 µV max offset, SO8 package, 36-V supply max, no REF pin | Fixed-output configuration simplifies layout but lacks ratiometric flexibility; higher offset limits 10-mV full-scale use | Choose for cost-sensitive industrial controls where REF flexibility is unnecessary and SO8 footprint is acceptable |
Compared with INA210AIDCKT, INA214AIDCKT trades gain for improved noise margin in mid-range shunt applications, while MAX4080TASA+ sacrifices offset performance and package size for simplified single-supply operation - neither offers pin compatibility, but both serve overlapping current-sensing functions in power management subsystems.

FAQ
What is the maximum common-mode voltage the INA210AIDCKT can measure?
The INA210AIDCKT supports a common-mode input voltage range of –0.3 V to 26 V, independent of its supply voltage. This allows direct high-side sensing on 24-V rails or negative-bias circuits. The specification is guaranteed across –40°C to +125°C and applies to both IN+ and IN– pins simultaneously. Exceeding 26 V requires external transient protection per TI's Application Note SBAA345.
Does the INA210AIDCKT require an external reference voltage?
Yes, the INA210AIDCKT requires an external voltage applied to the REF pin to set its output common-mode level. The REF pin accepts 0 V to V+ and directly offsets the output: VOUT = 200 × (VIN+ – VIN–) + VREF. For ratiometric operation, tie REF to a stable fraction of V+; for absolute output, connect to a precision voltage reference. Unbuffered resistive dividers degrade CMRR and must be avoided.
Can the INA210AIDCKT be used for bidirectional current sensing?
Yes, the INA210AIDCKT supports true bidirectional current sensing. When the shunt voltage polarity reverses (i.e., VIN– > VIN+), the output drops below VREF proportionally. With VREF biased at mid-supply (e.g., 2.5 V on 5-V rail), the output swings symmetrically around that point - enabling detection of charge and discharge currents in battery systems using a single INA210AIDCKT.
What is the typical bandwidth and slew rate of the INA210AIDCKT?
The INA210AIDCKT has a typical small-signal bandwidth of 14 kHz with a 10-pF load and a slew rate of 0.4 V/µs. These values are measured under standard conditions (VS = 5 V, VCM = 12 V). Bandwidth decreases with increasing capacitive load; slew rate limits large-signal step response - both are sufficient for DC–10 kHz current monitoring in DC-DC converters and motor control loops.
Is the INA210AIDCKT available in other packages besides SC70?
Yes, the INA210 is also offered in a 10-pin Thin UQFN (RSW) package (1.80 mm × 1.40 mm), but the specific orderable part INA210AIDCKT is exclusively the 6-pin SC70 variant. The UQFN version carries a different suffix (e.g., INA210AIRSAT) and has distinct pinout - including duplicated IN+ and IN– pins - and lower thermal resistance (107.3°C/W). No adapter or footprint compatibility exists between DCK and RSW packages.
