The ADXL312 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement up to ?12 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a serial port interface (SPI) (3- or 4-wire) or I2C digital interface.The ADXL312 is well suited for car alarm or black box 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 (2.9 mg/LSB) enables resolution of inclination changes of as little as 0.25?. A built-in FIFO facilitates using oversampling techniques to improve resolution to as little as 0.05? of inclination.Several special sensing functions are provided. Activity and inactivity sensing detects the presence or absence of motion and whether the acceleration on any axis exceeds a user-set level. These functions can be mapped to interrupt output pins. An integrated 32 level FIFO can be used to store data to minimize host processor intervention.Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.The ADXL312 is supplied in a small, thin 5 mm ? 5 mm ? 1.45 mm, 32-lead, LFCSP package.Applications Car alarm Hill start aid (HSA) Electronic parking brake Data recorder (black box)

Demonstration Circuit DC2748A features the LTC3315B dual 5V, 2A Synchronous Step-Down DC/DC regulators operating at 6MHz. One regulator provides a 1.8V output and the other provides 2.0V, both up to a 2A load. The LTC3315B supports adjustable output voltages from 0.5V to VIN, operating frequencies from 3MHz up to 10MHz. The LTC3315B is a compact, high efficiency, and high speed synchronous monolithic step-down switching regulator. Fast minimum on-time of 25ns enables high VIN to low VOUT conversion at high frequency. The DC2748A operating mode may be selected as Burst Mode operation, Skip mode or Forced Continuous (FC) mode. Setting JP1 to the FC/SYNC position will allow the LTC3315B to sync to a clock frequency from 3MHz to 10MHz. The LTC3315B operates in Forced Continuous mode when syncing to an external clock. The LTC3315B data sheet gives a complete description of the device, operation and application information. The data sheet must be read in conjunction with the demo manual.

Two outputs can be connected in parallel for a single 36A output solution with optional jumper resistors. The board allows the user to program how its output ramps up and down through the TRACK/SS pin. Remote output voltage sensing is available for improved output voltage regulation at the load point. An optional input inductor L1 reduces the EMI noise for noise sensitive applications. DC2268A can be easily inserted to an edge connector for testing and debugging.
