AD7985 数据手册和产品信息 | 亚德诺半导体
I am just studing to use your AD7985 with your datasheet page.19, Fig 27 CSB Mode, 3-Wire Without Busy Indicator Serial Interface Timing (SDI High) condition. Also I will be worked AD7985 with fix the procedure of conversion and acquition…
I have the AD7985 eval board and I am referring to the EVAL-AD7944_85_86EDZ manual (a pdf file got in the cd came with the board). I am trying to test the AD7985 with Beaglebone Black over SPI Interface. Few things are not clear.
1. Somewhere in the…
The 16-bit AD7985 was used together with a flexible sensor signal conditioning block which can be used for accurate smallsignal measurements in this reference circuit. The AD7985 has an input voltage range of 0-Vref (Vref can be externally…
This is the reference circuit about the AD8253 and AD7985.
There are differencial input ports in the AD8253 and I want to use this device for single input.
Then how can I connet the other input pin?
I have attached a list of some of the ADCs that fit your criteria of 2MSPS sampling rate or higher at resolution of 12bits or more.
You may also wanted to check the ADI website and do a parametric search (http://www.analog.com/ps/psthandler…
要确认这个问题，最好用示波器测量CNV, SCK, SDO波形，看一下。
I’m trying to decide which ADC to use for a high voltage front end. Here are the requirements for the ADC:
Fixed input range +/- 50V
16 bit resolution
10 Meg input impedance
1 MHz Bandwidth
2 or 3 MSPS or greater
Serial or SPI output
