AMC1311x-Q1 Automotive, High-Impedance, 2-V Input, Reinforced Isolated Amplifiers
1 Features
3 Description
- AEC-Q100 qualified for automotive applications:
The AMC1311-Q1 is a precision, isolated amplifier
- Temperature grade 1:
- 40°C to +125°C, TA
- Functional Safety-Capable
- Documentation available to aid functional safety system design
- 2-V, high-impedance input voltage range optimized for isolated voltage measurement
- Fixed gain: 1 with an output separated from the input circuitry by a capacitive isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 5 k VRMS according to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 and supports a working voltage of up to 1500 VRMS.
- Low DC errors:
- AMC1311-Q1:
The isolation barrier separates parts of the system that operate on different mon-mode voltage levels
- Offset error: ±9.9 m V (maximum) and protects the low-voltage side from voltages that
- Offset drift: ±20 µV/°C (typical) can cause electrical damage or be harmful to an
- Gain error: ±1% (maximum) operator.
- Gain drift: ±30 ppm/°C (typical)
- AMC1311B-Q1:
- Offset error: ±1.5 m V (maximum)
- Offset drift: ±10 µV/°C (maximum)
- Gain error: ±0.2% (maximum)
- Gain drift: ±40 ppm/°C (maximum)
- Nonlinearity: 0.04% (maximum)
- 3.3-V operation on high-side (AMC1311B-Q1)
- High CMTI: 100 k V/μs (AMC1311B-Q1)
- Missing high-side supply...
