IAM-20680HT

IAM-20680HT is a 6-axis automotive MotionTracking IMU from TDK InvenSense in an LGA package (3 x 3 x 0.75 mm) — the High-Temperature SmartAutomotive member of the IAM-20680 family, for in-cabin and chassis motion sensing that must survive hot automotive environments, and listed by TDK as Production. The selection point is the temperature ceiling: operation from −40 °C to +105 °C, where the base IAM-20680 stops at +85 °C. Verified figures: VDD 1.71–3.6 V; gyroscope ranges ±250/500/1000/2000 dps with sensitivities of 131/65.5/32.8/16.4 LSB/dps and rate noise of 0.005 dps/√Hz; accelerometer ranges ±2/4/8/16 g with sensitivities of 16384/8192/4096/2048 LSB/g; I2C and SPI interfaces; AEC-Q100 qualified. The +105 °C range with AEC-Q100 qualification is what carries this part into engine-adjacent and sun-loaded cabin locations that exclude consumer-grade IMUs. Selection advice: choose the HT code when the mounting location can exceed +85 °C; the IAM-20680HP shares the same headline electrical table and +105 °C range as the family's high-performance automotive option, so confirm the detailed datasheet grading against your requirement before choosing between HT and HP. For new designs do not substitute the base IAM-20680 — TDK lists it as Production (NRND) with the lower temperature ceiling. Parameters verified against the TDK Product Center listing for this exact code.
