Analog Devices Inc. has released iMEMS (integrated micro electro mechanical system) accelerometers in thin 4-by-4-by-1.45mm plastic Lead Frame Chip Scale Packages (LFCSP).

Claimed by the company as an industry's first, the ADXL32x family of accelerometers is designed for consumer applications, including mobile phones and smart handheld devices.

Operating on power supplies as low as 2.7V, the ADXL320 and ADXL321 dual-axis accelerometers with signal-conditioned voltage outputs typically consume 450?A, and can be power-cycled for greater battery life. Typical noise floor is 200?g/rtHz, allowing small tilt changes to be sensed using the narrow bandwidths (<10 Hz) typical of human motion. Bandwidths of 1Hz to 2kHz may be selected to suit the application.

The ADXL320 5g accelerometer addresses the integration requirements of cellphones for a variety of motion-sensing, tilt-sensing and inertial-sensing features. These new features include data entry, gaming, battery power management, menu and display control, gesture recognition, situational awareness, navigation and automatic portrait versus landscape display orientation. The product also enables hard drive protection systems and security features in notebook computers.

The ADXL321, with a 10g measurement range, enables vibration detection in consumer appliances such as washing machines and feed-forward compensation solutions for automotive DVD and CD drives.

The products are priced at $ 2.40 in quantities of 10,000 units.
