ADIS16255: Programmable Low Power Gyroscope
ADIS16250是ADI公司iSensorTM集成技术推出的小封装单芯片的完整角速度测量系统。通过使用嵌入式信号处理方案增强ADI公司的iMEMS(R)传感器技术,ADIS16250可以通过简单的SPI串行接口提供出厂校准的和数字可调节的传感器数据。该SPI接口可对陀螺仪、温度、电源电压的测量以及一个辅助的模拟输入端口提供访问。对校准的数字传感器数据访问的简便性,为开发商提供了一个立即可用的系统级器件,从而节省开发时间、成本和编程风险。
器件可以通过数字方式设置为三种不同测量范围：每秒+80度(80/sec)、每秒+160度(160/sec)、每秒+320度(320/sec)。通过芯片内置的一些特性可以很容易的实现最终系统的特定要求,包括单寄存器指令实现的自稳零重新校准,以及可编程的采样速率和频率响应。利用下述附加的功能可以进一步简化系统的复杂性,包括可配置的报警功能、辅助12 bit ADC、辅助12 bit DAC、可配置的数字I/O端口、数字自测试功能以及一个嵌入的温度传感器。系统功耗可通过ADIS16250的电源管理功能进行优化,包括中断驱动唤醒功能。
The ADIS16250/ADIS16255 are complete angular rate measurement systems available in a single compact package enabled by Analog Devices, Inc. iSensorTM integration. By enhancing Analog Devices iMEMS(R) sensor technology with an embedded signal processing solution, the ADIS16250/ADIS16255 provide factory-calibrated and tunable digital sensor data in a convenient format that can be accessed using a simple SPI serial interface. The ADIS16255 additionally provides an extended temperature calibration. The SPI interface provides access to measurements for the gyroscope, temperature, power supply, and one auxiliary analog input. Easy access to calibrated digital sensor data provides developers with a system-ready device, reducing development time, cost, and program risk.
The device range can be digitally selected from three different settings: ±80°/sec, ±160°/sec, and ±320°/sec. Unique charac-teristics of the end system are accommodated easily through several built-in features, including a single-command auto-zero recalibration function, as well as configurable sample rate and frequency response. Additional features can be used to further reduce system complexity, including:
- Configurable alarm function
- Auxiliary 12-bit ADC and DAC
- Two configurable digital I/O ports
- Digital self-test function
System power dissipation can be optimized via the ADIS16250/ ADIS16255 power management features, including an interrupt-driven wake-up. The ADIS16250/ADIS16255 are available in an 11 mm × 11 mm × 5.5 mm, laminate-based land grid array (LGA) package with a temperature range of -40°C to +85°C.
