GENERAL DESCRIPTION The ADIS16204 is a fully-contained programmable impact sensor in a single compact package enabled by the Analog Devices, Inc. iSensor™ integration. By enhancing the Analog Devices iMEMS® sensor technology with an embedded signal processing solution, the ADIS16204 provides tunable digital sensor data in a convenient format that can be accessed using a serial peripheral interface (SPI). The SPI provides access to measurements for dual-axis linear acceleration, a root sum square (RSS) of both axes, temperature, power supply, an auxiliary analog input, and an event capture buffer memory. Easy access to digital sensor data provides users with a system-ready device, reducing development time, cost, and program risk. Unique characteristics of the end system are accommodated easily through several built-in features, such as a single command in-system bias null/offset calibration, along with convenient sample rate control. The ADIS16204 offers the following embedded features, which eliminate the need for external circuitry and provide a simplified system interface: • Peak sample and hold • Programmable event recording (dual, 1K × 16 bit) • RSS output (total shock in the X-Y plane) • Configurable alarms • Auxiliary 12-bit ADC and DAC • Configurable digital I/O port • Digital self-test function The ADIS16204 offers two power management features for managing system-level power dissipation: low power mode and a configurable shutdown feature. The ADIS16204 is available in a 9.2 mm × 9.2 mm × 3.9 mm laminate-based land grid array (LGA) package with a tem- perature range of −40°C to +105°C. |
