成都国腾微电子公司日前宣布,他们已面向倒车雷达应用推出采用ASIC 设计的GM3101专用芯片。该芯片据称能有效降低倒车雷达产品开发的技术门槛,显著提高产品的灵敏度、可靠性和稳定性,可完全替代传统单片机方案,而其成本仅相当于单片机方案的60%。 GM3101具备四路超声波探头驱动接口,探头发送驱动信号的强度为5V @2 mA。此外,它内部还整合有多级运放、多路开关、比较器电路及大量的分离元件,而且外部电路十分简单。该芯片的其它特性还包括:
Chengdu Guoteng Microelectronics recently announced that they have launched GM3101 dedicated ASIC chip design for reversing radar applications. The chip is said to be able to effectively reduce the technical threshold of reversing radar product development, significantly improve product sensitivity, reliability and stability, can completely replace the traditional SCM program, and its cost is only equivalent to 60% of the SCM program. GM3101 has four ultrasound probe driver interface, the probe sends the drive signal strength of 5V @ 2 mA. In addition, it integrates multi-stage op amp, multiplexer, comparator circuit and a large number of separate components, and the external circuit is very simple. Other features of the chip include:
