AMC3330DWE

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.

AMC3330DWE features (concise):
- Isolated single-channel delta-sigma modulator with galvanic isolation between analog input and digital output
- Input optimized for low-level differential sensing (suitable for shunt/current-sense signals)
- SPI-like (serial) digital interface to a microcontroller for easy data transfer
- High isolation rating for safety and EMI robustness (reinforced isolation across the barrier)
- Low power consumption with support for automotive/industrial operating conditions
- Small 8-pin DWE package (compact footprint)
- Robust ESD protection and reliable operation over wide temperature ranges
