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.
How…

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.
Phenomenon: 1) Normal progression…
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…
Part Number: ADS7871 I'm having trouble setting up this ADC through the SPI bus using an Arduino. I tried to do some basic read commands, but I get nothing back from the chip's Dout.
Are there certain registers that need to be set up first? I…
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 these…
Is a 3.1V external reference voltage available for Vdd = 3.3V? In the datasheet in page 4, it says that the maximum input for the reference buffer is Vdd-0.2. Does this means that I can use an external reference of 3.1V either on: -BUFIN with buffer enabled…
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…
