Can anyone please provide me with the spice / lt spice file of AD7685. ??
Could anyone tell me an alternative for AD7685 and ADuM1402 in NI-Multisim13. Also not just in multisim please help me in finding an alternative for AD7685 and AduM1402.
I am using AD7685, and the mode is CS Mode 3-Wire with Busy.
In this mode, SDO goes high because it is a pull-up when the analog to digital conversion starts.
In the data sheet, the pull-up of SDO is 47KΩ.
In the pull-up of 47KΩ, it goes…

Can you tell me what you're using to provide the 5V rail? I noticed from your schematic that you're not using an ADC driver for this prototype. The input of the AD7685 is a dynamic, capacitive load, and a typical bench-top supply may…
手册中，AD7685 的Full-scale step 最大时间为 1.8us，指的是阶跃波形建立完成后，AD7685需要的采集时间是1.8us.
AD7685手册中，−3 dB Input Bandwidth的典型值为2MHz, 建立到16 bits的解析度误差，大概需要的建立时间为：12 * 0.5us = 6us.
I would like to know if there's a recommended practice for power-up the different supplies of the AD7685. I'm designing a battery operated device which has the following sections: Sensor, Signal Conditioning Circuitry, AD7685 and MCU.
I am using the AD7685, powered on +5V/-5V, as a transimpedance amplifier. I need to shift the output (when there is no current input) to -4.5V, but according to the data sheet I should not apply -4.5V to the positive input because the Input Voltage Range…
