AMC1200TDWVRQ1

The AMC1200TDWVRQ1 isolation amplifier is a highly qualified and versatile component tailored for automotive applications. With AEC-Q100 certification, it can operate in demanding temperature ranges, offers robust ESD protection, and ensures precise measurements with its ±250-mV input voltage range optimized for shunt resistors. This amplifier maintains excellent linearity, low offset error, and minimal noise, making it ideal for signal processing. It also features a high common-mode rejection ratio and certified galvanic isolation, ensuring safety and signal integrity. With a typical 10-year lifespan at its rated working voltage, the AMC1200TDWVRQ1 is an outstanding choice for automotive electronics, setting new standards for precision and reliability.

The AMC1200-Q1 is a precision isolation amplifier with the output separated from the input circuitry by a silicon dioxide (SiO2 ) barrier that is highly resistant to magnetic interference. This barrier is certified to provide galvanic isolation of up to 4250 VPEAK according to UL1577 and VDE V 0884-10. Used in conjunction with isolated power supplies, this device prevents noise currents on a high common-mode voltage line from entering the local ground and interfering with or damaging sensitive circuitry.

The input of the AMC1200-Q1 is optimized for direct connection to shunt resistors or other low-voltage level signal sources. The performance of the device supports accurate current control, resulting in systemlevel power saving and (especially in motor-control applications) lower torque ripple. The common-mode voltage of the output signal is automatically adjusted to either the 3-V or 5-V low-side supply.

The AMC1200-Q1 is available in a wide-body, 8-pin SOIC package (DWV) and a gullwing, 8-pin SOP package (DUB).
