Part Number: ADS7871 Hi team,
A customer is testing the ADS7871 and has a question on how to drive it.
According to the DS it should work. However, they are not receiving any data on the DOUT pin, the pin connections are shown in the figure below…

Hi team，
A customer doese not have company email so I help him to post this issue.
this issue is ADS7871 suddenly fails to output DOUT while in use. Occasionally, ADC values could not be sent to MCU.

Part Number: ADS7871 Tool/software: TI C/C++ Compiler Dear Sir,
I am using ADS7871 spi ADC interface with dspic33fj128mc706a controller. we can able to set register 7 . but we con't read the device id. Can you send the sample code for how to read the…
Hi Andrew,
OK - CCLK seems right, but it sounds like you've not got the reference enabled - take a look at the block diagram of Figure 15 (pg. 13). By default at power up, the reference and buffer are both powered off. Details on enabling the reference…
Part Number: ADS7871 Hi,
I would like to seek some clarifications on the problem that i’m having with ADS7871. I noticed that for few chips that i’m working on, there are some weird issues that seems odd. First of all, i’ll like to point out that…
Other Parts Discussed in Thread: ADS7871 We are seeing some inconsistency with the ADS7871 readings. A 1.3 voltage input would saturate the reading and cause a max reading of 8191 on one chip and not another. Every board has the same firmware enabling…
Other Parts Discussed in Thread: ADS7871 I am using an ADS7871. I would like the I/O port be configured for output to control the counter that tells the ADC when to start. I can read and write to all registers except register 5 (Digitial I/O state). I…
Other Parts Discussed in Thread: ADS7871 Hi
Since in my application it is not possible to reduce the analog input channel source impedance arbitrarily, I need some more details:
1. The Datasheet recommends to reduce CCLK, for a analog input channel…
Other Parts Discussed in Thread: ADS7871 , TUSB3410 Hello,
I am trying to interface with ADS7871 converter using a FTDI4232H. So far I couldn't achieve this. I tried using FTDI D2xx library but that didn't do much for me. I know that I need to use…
