A5350集成电路（IC）的传感器检测器接口规格书PDF中文资料

A5350属于集成电路（IC）的传感器检测器接口。由Allegro MicroSystems制造生产的A5350传感器和检测器接口该系列产品可执行信号调节、数据转换、激励生成和/或各种将传感器或变送器机构连接到主机设备所需的其他功能。示例包括用于 CCD 图像传感器的控制器、用于 4-20 mA 接口和类似应用的电流变送器、超声变送器前端、惠斯通电桥接口等。

The A5350CA is a low-current, CMOS circuit providing all of the required features for an ionization-type smoke detector. A networking capability allows as many as 125 units to be interconnected so that if any unit senses smoke, all units will sound an alarm. In addition, special features are incorporated to facilitate alignment and test of the finished smoke detector. This device is designed to comply with Underwriters Laboratories Specification UL217.

The internal oscillator and timing circuitry keeps standby power to a minimum by powering down the device for 1.66 seconds and sensing smoke for only 10 ms. Every 24 on/off cycles, a check is made for low battery condition. By substituting other types of sensors, or a switch for the ionization detector, this very-low power device can be used in numerous other battery-operated safety/security applications.

The A5350CA is supplied in a low-cost, 16-pin dual in-line plastic package. It is rated for continuous operation over the temperature range of 0°C to +50°C.
