Product details
Overview
AMC1301SDWV from Texas Instruments is a precision reinforced isolated amplifier optimized for shunt-based current sensing in high-voltage systems, featuring ±250-mV input range, fixed 8.2 V/V gain, ±0.2 mV max offset error, and 7070-VPK reinforced isolation per VDE 0884-17 - deployed in motor drives, frequency inverters, and onboard chargers.
For engineers reviewing the AMC1301SDWV datasheet, AMC1301SDWV pinout, AMC1301SDWV application, or AMC1301SDWV equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial temperature operation (–40°C to +125°C), and real-world diagnostic features including common-mode overvoltage detection and missing supply monitoring.
Technical Context
The AMC1301SDWV implements galvanic isolation via a capacitive barrier certified to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577, supporting up to 1 kVRMS working voltage and 7000-VPK transient isolation. Its differential analog input accepts ±250 mV directly across shunt resistors while rejecting common-mode voltages up to VDD1 – 2 V.
It delivers rail-to-rail differential output (±2.49 V) with 190–210 kHz bandwidth, 15 kV/µs CMTI, and integrated system-level diagnostics: common-mode overvoltage detection with 60-mV hysteresis and high-side supply loss detection triggering failsafe output at –2.545 V.

Pinout & Package
AMC1301SDWV is housed in a wide-body 8-pin SOIC (DWV) package measuring 5.85 mm × 7.50 mm, with creepage and clearance ≥8.5 mm and internal DTI ≥0.021 mm - designed for reinforced insulation compliance in high-voltage PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD1 | High-side power supply | Provides 3.0–5.5 V to isolated input stage; requires local decoupling near pin 1. |
| 2 - INP | Noninverting analog input | Accepts positive shunt terminal voltage; must share DC path to GND1 with INN. |
| 3 - INN | Inverting analog input | Accepts negative shunt terminal voltage; defines common-mode input with INP. |
| 4 - GND1 | High-side analog ground | Reference for input circuitry and shunt resistor; galvanically separated from GND2. |
| 5 - GND2 | Low-side analog ground | Reference for output stage and downstream ADC; tied to system controller ground. |
| 6 - OUTN | Inverting analog output | Differential output leg; used with OUTP to drive fully differential ADC inputs. |
| 7 - OUTP | Noninverting analog output | Differential output leg; provides ±2.49 V swing referenced to VCMout = 1.44 V. |
| 8 - VDD2 | Low-side power supply | Provides 3.0–5.5 V to isolated output stage; decoupling required near pin 8. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated current-sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AMC1301QDWVQ1 | Automotive-grade variant qualified to AEC-Q100 Grade 1 (–40°C to +125°C); identical electrical specs but enhanced process controls and traceability. | Required for automotive OEM designs needing PPAP documentation and zero-defect reliability targets. | Select AMC1301QDWVQ1 only when automotive qualification and extended lifetime traceability are mandated - not a drop-in replacement for industrial use. |
| ISO224BDWVR | Higher gain (8.2 V/V same), wider input range (±10 V), lower offset drift (±1 µV/°C), but no common-mode overvoltage detection feature. | Better suited for voltage sensing or wide-range current sensing where diagnostic features are secondary to ultra-low drift. | Choose ISO224BDWVR when higher input dynamic range or tighter drift spec is critical - AMC1301SDWV remains preferred for shunt-based motor control with integrated diagnostics. |
Compared with AMC1301QDWVQ1, the AMC1301SDWV offers identical performance in industrial environments without automotive qualification overhead; versus ISO224BDWVR, it trades wider input range for built-in fault detection - making it more robust for cost-sensitive, safety-aware inverter designs.

FAQ
What is the maximum working voltage supported by the AMC1301SDWV?
The AMC1301SDWV supports a maximum rated isolation working voltage of 1000 VRMS per DIN EN IEC 60747-17 (VDE 0884-17). This allows safe operation in systems with up to 1000 VRMS continuous common-mode voltage across the isolation barrier - such as 690 VAC industrial drives or 800 VDC EV battery interfaces. The device also withstands 5000 VRMS for 1 minute per UL1577.
Does the AMC1301SDWV require external gain-setting resistors?
No, the AMC1301SDWV features a fixed internal gain of 8.2 V/V and does not require external gain-setting resistors. This eliminates resistor tolerance, temperature drift, and layout sensitivity issues - ensuring consistent gain accuracy of ±0.3% over temperature and simplifying PCB design for AMC1301SDWV-based current sensing circuits.
How does the common-mode overvoltage detection work on the AMC1301SDWV?
The AMC1301SDWV monitors the average voltage at INP and INN relative to GND1. When (INP + INN)/2 exceeds VDD1 – 2 V, it triggers common-mode overvoltage detection with 60-mV hysteresis. Upon detection, the output enters a known failsafe state (–2.545 V differential), providing immediate fault signaling without external comparators - a key diagnostic function confirmed in AMC1301SDWV's datasheet Section 6.9.
Can the AMC1301SDWV operate with different supply voltages on each side?
Yes, the AMC1301SDWV supports independent supplies: VDD1 (high-side) and VDD2 (low-side) each operate from 3.0 V to 5.5 V. Typical configurations include 5 V on VDD1 (for noise margin in high-voltage domains) and 3.3 V on VDD2 (to interface with modern low-voltage microcontrollers), as validated in AMC1301SDWV's Recommended Operating Conditions table (Section 6.3).
What is the purpose of the failsafe output behavior in the AMC1301SDWV?
The AMC1301SDWV asserts a defined failsafe differential output voltage of –2.545 V when detecting either common-mode overvoltage or missing high-side supply (VDD1). This unambiguous signal enables downstream controllers to distinguish fault conditions from valid measurements - a critical safety feature for AMC1301SDWV deployments in motor protection, OBC shutdown, and UPS overload handling.
