The NSI1311-DSWVR is a 5-pin isolated delta-sigma modulator IC. Its key functions and pinout are:
1. VDD1 (Pin 1): Primary-side power supply (3.3V or 5V).
2. GND1 (Pin 2): Primary-side ground.
3. IN+ (Pin 3): Non-inverting analog input.
4. IN– (Pin 4): Inverting analog input.
5. VDD2 (Pin 5): Secondary-side power supply (3V to 5.5V).
It provides high-precision isolation (up to 5kV RMS) for analog signals, converting differential inputs into a 1-bit PDM (Pulse-Density Modulation) output via its internal clock. Typical applications include current sensing in motor control, power supplies, and industrial systems.

The NSI1311-DSWVR is typically available in a SOIC-8 package. This surface-mount package is compact and widely used for integrated circuits, offering reliable performance in space-constrained applications. Its small outline (SOIC) design ensures compatibility with standard PCB assembly processes. For exact specifications, refer to the manufacturer's datasheet.
