AMC1411QDWLRQ1

AMC1411QDWLRQ1 is TI’s single-channel galvanically isolated amplifier in the AMC1411 family. It provides isolation between a high-voltage primary domain (where the sense input is referenced) and a low-voltage secondary domain that interfaces with a microcontroller. The device integrates signal conditioning and an isolation barrier, enabling safe measurement of low-level signals (e.g., shunt current or small voltages) in motor drives, renewable-energy inverters, and power supplies, without exposing the controller to high common-mode voltages. Features typically include: one isolated channel, input range of a few tens to hundreds of millivolts, fixed or selectable gain, rail-to-rail output, low input offset and drift, fast propagation delay, and robust ESD/EMI immunity, plus an isolated supply option on the secondary side. The QDWLRQ1 suffix denotes packaging and temperature rating. For exact specs, pinout, and application notes, refer to the AMC1411QDWLRQ1 datasheet on TI’s website.

Equivalent parts depend on exact specs (isolation voltage, channel count, interface, speed, supply). Closest TI siblings to AMC1411QDWLRQ1 are AMC1410/AMC1412/AMC1413. External equivalents vary; look for isolated ADCs/amplifiers with a matching interface (SPI), isolation rating, and performance from Analog Devices and others. For exact cross-reference, use TI’s Cross-Reference tool or share your required specs.

Pin count: 16 pins.
Function: Single‑channel isolated amplifier with galvanic isolation between input and output sides (differential input on the primary side, amplified isolated output on the secondary side; separate supplies for each side).

Manufacturer: Texas Instruments (TI).
What kind of company: TI is a global semiconductor company that designs and manufactures analog and mixed-signal ICs and embedded processing solutions.
