The AMC3330DWER from Texas Instruments is a high-precision, reinforced isolated amplifier designed for voltage sensing applications. It integrates a DC/DC converter, enabling single-supply operation from the low-side of the device. This amplifier supports a ±1V input voltage range, making it optimized for accurate voltage measurements with high input impedance.
Key electrical characteristics include a fixed gain of 2.0, low DC errors with a maximum gain error of ±0.2% and offset error of ±0.3mV. The device boasts excellent stability with a gain drift of ±45ppm/°C and offset drift of ±4µV/°C. It offers high common-mode transient immunity (CMTI) of 85 kV/µs (min) and operates across a wide temperature range of -40 to 125°C.
The reinforced capacitive isolation barrier is certified to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 standards, providing robust protection. It has a withstand isolation voltage of 4250 Vrms and a working isolation voltage of 1200 Vrms. The AMC3330DWER is housed in a SO-MOD (DWE) package with dimensions of 10.3 mm x 10.3 mm and an area of 106.09 mm².
This isolated amplifier is suitable for systems requiring separation of different common-mode voltage levels and protection of low-voltage circuitry. It meets CISPR-11 and CISPR-25 EMI standards and includes system-level diagnostic features.
