- Low DC errors:
- Offset error: ±0.2 mV (max)
- Offset drift: ±3 µV/°C (max)
- Gain error: ±0.3% (max)
- Gain drift: ±50 ppm/°C (max)
- Nonlinearity: 0.03% (max)
- 3.3-V operation on high-side and low-side
- System-level diagnostic features
- Safety-related certifications:
- 7070-V PK reinforced isolation per DIN EN IEC 60747-17 (VDE 0884-17)
- 5000-V RMS isolation for 1 minute per UL1577
- Fully specified over the extended industrial temperature range: –40°C to +125°C
The AMC1301 is a precision, isolated amplifier with an output separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation of up to 7070 V PEAK according to the DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 standards, and supports a working voltage up to 1 kV RMS.
The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-side from voltage levels that can cause electrical damage and are potentially harmful to an operator.
The input of the AMC1301 is optimized for direct connection to shunt resistors or other low voltage-level signal sources. The excellent DC accuracy and low temperature drift supports accurate current control in onboard chargers (OBC), DC/DC converters, frequency inverters, or other high-voltage applications. The integrated common-mode overvoltage and missing high-side supply voltage detection features of the AMC1301 simplify system-level design and diagnostics.
The AMC1301 is fully specified over the extended industrial temperature range of –40°C to +125°C and is available in a wide-body 8-pin SOIC (DWV) package. The AMC1301S is specified over the temperature range of –55°C to +125°C.
