Earlier I introduced a classic sensor to our customers: “Why the decade-old STK8321 is still mainstream today?”

Today, let’s look at its sister model—the STK8325, a compact, high-performance 3-axis MEMS accelerometer that’s ideal for applications demanding accuracy and reliability.

The sensor offers ±2g, ±4g, and ±8g full-scale ranges in an ultra-small 2.0 × 2.0 × 1.0 mm package. With low power consumption and robust performance, it’s a great fit for smartphones, wearables, and activity trackers.
