Product details
Overview
INA2180A1IDSGT from Texas Instruments is a dual-channel, high-precision current-sense amplifier with 20 V/V fixed gain, –0.2 V to +26 V common-mode input range, 350 kHz bandwidth, ±150 µV max offset at 0 V CM, and 2 V/µs slew rate-designed for bidirectional current monitoring in motor control and battery management systems.
For engineers reviewing the INA2180A1IDSGT datasheet, INA2180A1IDSGT pinout, INA2180A1IDSGT application, or INA2180A1IDSGT equivalent, this device delivers low-drift, rail-to-rail output swing, ±1% max gain error, and dual-channel integration in an 8-pin WSON package-enabling compact, high-accuracy shunt-based current sensing without external gain resistors.
Technical Context
The INA2180A1IDSGT implements a precision instrumentation amplifier architecture with integrated matched resistor network for 20 V/V gain, enabling stable gain accuracy across temperature (±1% max) and minimizing drift (1 µV/°C max offset drift). Its input stage operates over –0.2 V to +26 V common-mode voltage independent of 2.7–5.5 V supply, supporting both high-side and low-side sensing topologies.
Each channel features independent IN+ and IN– inputs referenced to GND, with rail-to-rail output swing (VS – 30 mV / GND + 0.5 mV), 260 µA per channel quiescent current (500 µA total), and 40 nV/√Hz input-referred noise-optimized for real-time current feedback in closed-loop power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 20 V/V fixed-eliminates external resistor matching errors and reduces layout sensitivity in production designs. |
| Common-mode range | –0.2 V to +26 V-supports direct sensing on 24-V bus rails, including reverse-polarity and ground-referenced shunts. |
| Bandwidth | 350 kHz-enables accurate capture of fast transient currents in PWM-driven motor phases and switching converters. |
| Offset voltage | ±150 µV max at VCM = 0 V-ensures sub-millivolt-level current resolution with 10-mΩ shunts at low load currents. |
| Slew rate | 2 V/µs-maintains fidelity during rapid current step changes, critical for overcurrent fault detection within microseconds. |
| Supply voltage | 2.7 V to 5.5 V-compatible with standard logic rails and enables operation from single Li-ion or 3.3-V system supplies. |
| Quiescent current | 500 µA max (dual-channel)-supports always-on current monitoring in battery-powered industrial sensors and portable equipment. |
Pinout & Package
The INA2180A1IDSGT is housed in an 8-pin, 2.0 mm × 2.0 mm WSON package (DSG) with exposed thermal pad (optional GND connection). Pin 1 is OUT1; pin 8 is VS; pins 4 and 5 are GND and IN+2 respectively-matching TI's standardized dual-channel current-sense pinout for layout reuse.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 (Pin 1) | Analog output | Channel 1 voltage output proportional to sensed current; rail-to-rail swing supports full ADC dynamic range utilization. |
| IN–1 (Pin 2) | Analog input | Negative input for channel 1; connects to load side of shunt in high-side config or ground side in low-side config. |
| IN+1 (Pin 3) | Analog input | Positive input for channel 1; connects to bus-voltage side of shunt in high-side config or load side in low-side config. |
| GND (Pin 4) | Analog ground | Reference node for all analog circuitry; must be tied to low-impedance system ground plane for noise immunity. |
| IN+2 (Pin 5) | Analog input | Positive input for channel 2; electrically isolated from channel 1-enables independent current monitoring of two circuits. |
| IN–2 (Pin 6) | Analog input | Negative input for channel 2; shares same common-mode tolerance and input bias specs as channel 1. |
| OUT2 (Pin 7) | Analog output | Channel 2 voltage output; identical AC/DC performance to OUT1-supports synchronous dual-current sampling. |
| VS (Pin 8) | Power supply | Single 2.7–5.5 V analog supply; decoupling with 0.1 µF ceramic capacitor required adjacent to pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 20 V/V gain network | Matched thin-film resistors minimize gain error (±1% max) and reduce temperature-induced drift vs discrete solutions. |
| –0.2 V to +26 V common-mode range | Enables direct sensing on automotive 12-V/24-V buses and industrial 24-V DC systems without level-shifting circuitry. |
| Dual-channel independence | Channels share supply but have fully isolated signal paths-no crosstalk (≥110 dB at 10 kHz) and no shared input errors. |
| Rail-to-rail output swing | Output drives within 30 mV of VS and 0.5 mV of GND-maximizes usable ADC input range and improves measurement SNR. |
| Low quiescent current | 500 µA max at TA = –40°C to +125°C-supports continuous current monitoring in thermally constrained enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel current-sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA226AIRSAT | I²C digital output, 16-bit ADC integrated; 0.1% gain error; 10 µV offset; requires external MCU interface. | Best for systems needing programmable gain, alert thresholds, and digital calibration-not for analog feedback loops. | Select when digital BOM consolidation and host-controlled configuration outweigh need for analog immediacy. |
| MAX40056ATA+T | Single-channel, 100 V/V gain, 1.5 MHz bandwidth, ±100 µV offset; 5-pin SOT23 package. | Higher bandwidth suits ultrafast overcurrent shutdown; lacks dual-channel integration and 26-V CM range. | Choose for single-point high-speed protection where space is tighter and dual-channel redundancy is unnecessary. |
Compared with INA226AIRSAT and MAX40056ATA+T, the INA226AIRSAT adds digital flexibility at cost of analog latency and external component dependency, while the MAX40056ATA+T trades channel count and common-mode capability for raw speed-making INA2180A1IDSGT optimal for compact, dual-analog, wide-CM industrial current sensing.

FAQ
What is the maximum common-mode voltage supported by the INA2180A1IDSGT?
The INA2180A1IDSGT supports a common-mode input voltage range of –0.2 V to +26 V, enabling direct sensing on 24-V industrial buses and automotive systems without external level-shifting components. This specification is guaranteed across the full operating temperature range of –40°C to +125°C and applies independently to each channel of the INA2180A1IDSGT.
Does the INA2180A1IDSGT require external gain-setting resistors?
No-the INA2180A1IDSGT integrates a precision-matched internal resistor network configured for 20 V/V fixed gain. This eliminates external resistor selection, layout sensitivity, and temperature-induced gain drift, delivering ±1% maximum gain error across –40°C to +125°C-verified in production test for every unit of the INA2180A1IDSGT.
What is the typical quiescent current consumption of the INA2180A1IDSGT?
The INA2180A1IDSGT draws a maximum of 500 µA total quiescent current across both channels at TA = –40°C to +125°C and VS = 5 V. At 25°C and 5 V, typical consumption is 355 µA-making it suitable for always-on current monitoring in battery-backed or energy-constrained industrial nodes using the INA2180A1IDSGT.
Can the INA2180A1IDSGT be used for high-side current sensing?
Yes-the INA2180A1IDSGT is explicitly designed for both high-side and low-side current sensing. Its –0.2 V to +26 V common-mode range allows the IN+ and IN– inputs to operate far above the VS supply rail, enabling direct connection across shunts on positive 24-V bus lines while powered from a separate 3.3-V or 5-V domain-fully supported in all INA2180A1IDSGT applications.
What package type is used for the INA2180A1IDSGT?
The INA2180A1IDSGT uses an 8-pin WSON package (DSG), measuring 2.0 mm × 2.0 mm with an exposed thermal pad. This compact, surface-mount package supports high-density PCB layouts and provides enhanced thermal performance versus VSSOP-confirmed in TI's SBOS741H datasheet for the INA2180A1IDSGT.
