ADI 微转换器突破性的技术ADI

简介:ADI 微转换器突破性的技术

问:ADμC812是贵公司最新推出的全集成12位数据采集系统,它和同类产品比较有什么特点?
答: ADuC812 有8052MCU,8Kflasn闪存,另加8通道12Bit A/D 和2个D/A, 是一个真正的单片数据采集处理器。
Of couse, we have other SOC chip such as DSP + Audio converter/ Audio D/A --- AD73422/ AD73522.

问:1:串行还是并行?
2:转换时间?
3:支持68000系列吗?
答: 1. I think you mean the program download mode, then serial download is ok for on-circuit, parallel only for factory download.
2. The fastest convertion time for ADuC812 is 200KHZ
3. Not support for 68000

问:数据采集的速度和通道数量的限制?转换器的突出优点?
答: The fastest conversion speed for ADuC812 is 200khz. You can convert 8 channels using on chip switch. This chip integrates converter (ADC, DAC), MCU, Flash and SPI/I2C/UART, and other communication on one system. Therefore it"s a system on chip for dat

问:ADI微转换器突破性的技术在光通信领域的应用有哪些?能具体说明吗?谢谢!
答: 用于光功率控制和监测,另,加ADN2841, ADN8830, ADN8809,ADN8831 以及其他 ADN 系列均用于光通讯。

问:在我所设计的ADuC812控制器的3个应用中,重新编程后常发生系统工作不正常的情况,常导致仿真开发系统不能进入。

请赐教,谢谢!
答: The AuC812/16/24 needs to provide an external reset signal from reset generator(ADM809/810) to get correct reset timing. You should try this.

问:有关ADmC812“自校准” 功能的一些特点, 我如何使用这些功能?它能校准ADmC812的ADC失调误差和增益误差吗?

答: There is a tech note on our web to talking about this. The Tech note number UC005. Please check it out on our web.

问:请问ADI公司目前就高速测量信号采集(如光的偏振态)的控制和接口电路有何较好的解决方案?
答: Please contact our local office.

问:我能把一个高阻抗模拟信号源直接接到ADmC812的输入端吗?是否必须先把信号缓冲?

答: Yes, you need the buffer in the front.

问:ADuC812中的ADC calibration register是否需要用户写入?如何得到应该写入的校准数据?
答: No need for user to write it, as ADuC812 have power on configuration program, before running user code. The cablibration coefficient is factory loaded. Therefore unless you"ve special request, then you can do user calibration that refer to the code ex

问:再请问:
1。ADUC812的片内基准电压为2。5V,是否对3V和5V工作电压都一样?
2。ADC中的噪音如何降低到最低限度?是用软件还是硬件?
答: 1. Yes.
2. You can use a RC filter to cutdown band width first. And then, you can do digital filter and then decimate down to a lower sample rate to get process gain.
