Product details
Overview
INA180A4IDBVT from Texas Instruments is a single-channel, high-side/low-side current-sense amplifier with fixed 200 V/V gain, –0.2 V to +26 V input common-mode range, ±500 µV max offset at 12 V VCM, and 2 V/µs slew rate-designed for precision battery monitoring and motor overcurrent detection in 2.7–5.5 V systems.
For engineers reviewing the INA180A4IDBVT datasheet, INA180A4IDBVT pinout, INA180A4IDBVT application, or INA180A4IDBVT equivalent, this page delivers verified specifications, SOT-23 pin mapping, real-world use cases in power management and solar inverters, and two validated alternative parts with documented technical differences.
Technical Context
The INA180A4IDBVT employs a precision matched-resistor gain network (200 V/V) to minimize gain error (±1% max) and temperature drift (1 µV/°C max), enabling accurate current measurement across –40°C to +125°C. Its rail-to-rail output stage supports 0.0005 V to VS – 0.03 V swing into 10 kΩ loads.
It operates with 260 µA max quiescent current and achieves 105 kHz small-signal bandwidth (CLOAD = 10 pF), optimized for fast transient response in closed-loop motor control and real-time battery charge/discharge monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 200 V/V fixed-enables direct conversion of 10 mV sense voltage to 2 V output, simplifying ADC interface design |
| Common-mode range | –0.2 V to +26 V-supports high-side sensing on 24-V bus rails without level-shifting circuitry |
| Offset voltage | ±500 µV max at VCM = 12 V-limits current measurement error to ≤0.5% at 2.5 mΩ shunt with 1 A full-scale |
| Bandwidth | 105 kHz-captures rapid current transients in PWM-driven motor phases or DC-DC converter switching events |
| Slew rate | 2 V/µs-ensures <500 ns output settling for 1-V step, critical for overcurrent fault response timing |
| Supply voltage | 2.7 V to 5.5 V-compatible with standard microcontroller I/O domains and low-voltage battery systems |
| Quiescent current | 260 µA max-enables always-on current monitoring in energy-constrained IoT and portable devices |
Pinout & Package
The INA180A4IDBVT is packaged in a 5-pin SOT-23 (DBV) with Pinout A configuration (per TI SBOS741H Rev H). This compact 2.90 mm × 1.60 mm surface-mount package supports automated assembly and thermal dissipation up to 197.1°C/W junction-to-ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Analog output-delivers amplified, referenced voltage proportional to sensed current; requires no external pull-up |
| 2 | GND | Analog ground-must be connected to system power ground plane with low-impedance path to minimize noise coupling |
| 3 | IN+ | Positive input-connects to bus-voltage side of shunt in high-side config or load side in low-side config |
| 4 | IN– | Negative input-connects to load side of shunt in high-side config or ground side in low-side config |
| 5 | VS | Power supply-accepts 2.7–5.5 V; bypassing with 0.1 µF ceramic capacitor to GND is mandatory for stability |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 200 V/V gain | Eliminates external gain-setting resistors, reducing BOM count and layout sensitivity to parasitic capacitance |
| –0.2 V to +26 V common-mode range | Enables bidirectional current sensing on negative-ground or floating high-voltage rails without auxiliary supplies |
| ±1% max gain error | Reduces calibration burden in production test-supports <1% total current measurement uncertainty at room temperature |
| 1 µV/°C max offset drift | Maintains accuracy across automotive (-40°C to +125°C) and industrial temperature ranges without software compensation |
| 260 µA max quiescent current | Permits integration into always-on subsystems such as battery fuel gauging or standby power monitors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-sense amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA240A4IDR | 200 V/V gain, wider VCM (–4 V to +80 V), higher quiescent current (1.1 mA), SOIC-8 package | Required for >26 V bus voltages (e.g., 48 V industrial systems); not drop-in due to larger footprint and different pinout | Select when sensing on 36–80 V rails; verify PCB layout change and thermal derating for 1.1 mA IQ |
| MAX40056AUB+T | 200 V/V gain, VCM = –0.1 V to +65 V, 1.5 µV/°C offset drift, 650 kHz bandwidth, 8-pin µMAX | Higher bandwidth suits ultrafast protection in GaN-based converters; drift spec looser than INA180A4IDBVT | Choose for >500 kHz signal fidelity needs; accept higher drift if ambient temperature variation is limited |
Compared with INA240A4IDR and MAX40056AUB+T, the INA180A4IDBVT offers lowest quiescent current and tightest offset drift in the 26 V VCM class, making it optimal for thermally constrained, battery-powered, or wide-temperature industrial designs where long-term accuracy matters more than extreme bandwidth or ultra-high voltage support.

FAQ
What is the maximum common-mode voltage supported by the INA180A4IDBVT?
The INA180A4IDBVT supports a common-mode input voltage range of –0.2 V to +26 V, enabling direct high-side sensing on 24-V industrial buses or low-side sensing near ground without level-shifting circuitry. This specification is guaranteed across the full –40°C to +125°C operating temperature range and is independent of the 2.7–5.5 V supply voltage.
Does the INA180A4IDBVT require external gain-setting resistors?
No, the INA180A4IDBVT integrates a factory-trimmed, matched-resistor gain network set to 200 V/V. This eliminates external resistors, reduces layout sensitivity to parasitic effects, and ensures ±1% maximum gain error over temperature-critical for production-calibration efficiency and long-term stability in the INA180A4IDBVT.
What is the typical bandwidth and slew rate of the INA180A4IDBVT?
The INA180A4IDBVT has a small-signal bandwidth of 105 kHz (with 10 pF load) and a large-signal slew rate of 2 V/µs. These values enable accurate capture of fast current transients in PWM motor control and DC-DC converter applications, with output settling time under 500 ns for 1-V steps-key performance metrics confirmed in the INA180A4IDBVT datasheet.
Which SOT-23 pinout configuration does the INA180A4IDBVT use?
The INA180A4IDBVT uses Pinout A per TI SBOS741H: Pin 1 = OUT, Pin 2 = GND, Pin 3 = IN+, Pin 4 = IN–, Pin 5 = VS. This configuration differs from Pinout B (used by INA180Bx variants), so PCB layout must match the correct pin mapping to avoid functional failure in the INA180A4IDBVT.
What is the maximum quiescent current consumption of the INA180A4IDBVT?
The INA180A4IDBVT draws a maximum quiescent current of 260 µA at 25°C and up to 300 µA across the full –40°C to +125°C temperature range. This ultra-low IQ enables continuous current monitoring in battery-powered systems without significant runtime impact-verified in the electrical characteristics table of the INA180A4IDBVT datasheet.
