Accelerometer X, Y, Z Axis ±2g, 4g, 8g, 16g 0.05Hz ~ 1.6kHz 14-LGA (3x5) The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Free-fall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins. An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation. The ADXL345 is supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-lead, plastic package. ► Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical) ► Power consumption scales automatically with bandwidth ► User-selectable resolution ► Fixed 10-bit resolution ► Full resolution, where resolution increases with g range, up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor in all g ranges) ► Embedded memory management system with FIFO technology minimizes host processor load ► Single tap/double tap detection ► Activity/inactivity monitoring ► Free-fall detection ► Supply voltage range: 2.0 V to 3.6 V ► I/O voltage range: 1.7 V to VS ► SPI (3- and 4-wire) and I2C digital interfaces ► Flexible interrupt modes mappable to either interrupt pin ► Measurement ranges selectable via serial command ► Bandwidth selectable via serial command ► Wide temperature range (−40°C to +85°C) ► 10,000 g shock survival ► Pb free/RoHS compliant #commonpartslibrary #sensor #transducer #accelerometer

The HT8950/HT8950A provide two special effects: Vibrato and Robot. The Vibrato effect is generated by alternating the frequency of an input signal up and down at a rate of 8Hz. The Robot function, on the other hand, converts an input voice into a Robot voice. Both effects can be selected depending on which pin is triggered, either ROB or VIB. For the output frequency level shifting, the chips provide seven steps which can be selected #CommonPartsLibrary #IntegratedCircuit

The PAT9125EL-TKIT from PixArt Imaging Inc. is a low-power optical tracking miniature chip designed for precise motion detection using laser-based optical navigation technology. It integrates both the optical sensor and VCSEL laser light source into a single compact package, enabling accurate tracking even on smooth or glossy surfaces. This device captures sequential surface images and processes them internally to determine movement direction, speed, and displacement (X/Y data), which can be accessed by a host controller via digital interfaces. It is particularly suited for space-constrained, battery-powered, and enclosed systems, eliminating the need for mechanical components like code wheels or special surface markings. Key Features Integrated optical sensor + VCSEL laser (850 nm) in a single package No external lens required, simplifying design Wide depth of field (DOF): 1–30 mm, even on reflective surfaces Programmable resolution up to ~1275 CPI Supports I²C (TKIT) interface (SPI variant available as TKMT) Motion detection interrupt output Built-in oscillator (no external clock needed) Low power consumption: Run: ~0.7 mA Sleep: down to 10 µA Power-down: ~5 µA Pre-calibrated laser (no calibration required) IEC/EN 60825-1 Class 1 eye-safe laser compliant Key Specifications Supply Voltage: VDD: 1.7–3.6 V VLD (laser): 2.7–3.6 V Max Tracking Speed: up to ~30 inches/sec Package: 8-pin LGA (3.5 × 3.2 × 1.0 mm) Interface: I²C (for TKIT variant)
