Overview
Description
AMC3330DWE is a Texas Instruments isolated delta-sigma modulator. It provides galvanic isolation between a low‑level analog input (for sensing across a shunt or similar sensor) and a digital, SPI‑style output that can be read by a microcontroller or DSP. The device is a single-channel, high‑voltage‑isolation solution intended for isolated sensing in power electronics.
Key features (typical): one input channel, isolated digital output, SPI-compatible interface (SCLK, CS, SDI/SDO), and a specified isolation voltage between the input and output domains. It’s designed for harsh environments common in motor drives, power supplies, inverters, and renewable energy applications, where accurate, noise‑robust sensing is needed across a high common‑mode voltage.
The DWE suffix denotes a specific package/grade variant. In multi‑chip sensor chains, AMC3330DWE is commonly paired with isolated front-ends (e.g., AMC1300/1311) to form complete isolated current/voltage sensing solutions.
