I2C Address
- Determined by strapping Pin 7 (TEST) and Pin 39–48 (reserved). Default:
0x38(7-bit).
Important Observation:
- No suffix = Fixed output (often 3.3V)
- Suffix letter after the number indicates variation.
- On very small packages (SOT-23-5), only a 2-3 character code exists (e.g.,
X1A). You must cross-reference with an internal factory code.
Pro Tip: Always measure the output pin with a multimeter if the marking is ambiguous. Never assume voltage.
