AMC1311DWVR

The Texas Instruments AMC1311DWVR is a high-impedance, 2-V input, reinforced isolated amplifier optimized for isolated voltage measurement. It offers a fixed gain of 1 and low DC errors, with specific performance metrics detailed for both AMC1311 and AMC1311B variants regarding offset error, offset drift, gain error, and gain drift.

This device provides robust isolation, with a withstand isolation voltage of 5000 Vrms and a transient isolation voltage of 7000 VPK, meeting reinforced isolation standards per DIN EN IEC 60747-17 and UL1577. It boasts high Common Mode Transient Immunity (CMTI), with a minimum of 15 kV/µs and up to 100 kV/µs for the AMC1311B variant.

The AMC1311DWVR operates over an extended industrial temperature range of -40°C to +125°C. It is housed in an 8-pin SOIC (DWV) package with dimensions of 5.85 mm x 11.5 mm, providing a package area of 67.275 mm². Key features include a missing high-side supply indication and suitability for 3.3-V operation on the high side for the AMC1311B.

This isolated amplifier is suitable for applications requiring precise voltage monitoring in harsh electrical environments, such as motor control, power supplies, and battery management systems where galvanic isolation is critical for safety and signal integrity.
