Part Number: ADS7841-Q1 Other Parts Discussed in Thread: ADS7841 Hello,
Good day.
We would like to know the behavior of the below mentioned components by abrupt power shutdown cases. How component will affect from such incidents.
Any HW Impact to…
Part Number: BOOSTXL-ADS7841-Q1 Other Parts Discussed in Thread: ADS7841 Tool/software: Hi,
I am currently working with the ADS7481-Q1 EVM ( BOOSTXL-ADS7841-Q1) and have encountered some difficulties in obtaining accurate ADC values.
I have interfaced…
Part Number: ADS7841 Other Parts Discussed in Thread: TMS320F28379D , Dear sir/madam,
im trying to interface tms320f28379d with ads7841 via spi but getting random junk with or w/o connecting voltage to selected channel through control byte .
check…
Sure, BUSY indicates when the device is making the analog measurment, so it is best there there is no movement within the device during this time, such as clocking.
You can use BUSY to monitor when the device is in this state and use the falling edge…
Hello Tran,
YOur scope shot looks good thus far. Each communication between the processor and the converter consists of eight clock cycles. But, One complete conversion is accomplished with three serial communications, for a total of 24 clock cycles…
Hi Alex,
Happy to hear that it's working now! I suppose it really depends on how you connected the EVM with your processor. Pin 7 of the ADS7841 also connects to U5 pin 3, which comes through via pin U5 pin 6. If the SHDN_TIVA signal was left to float…
Part Number: BOOSTXL-ADS7841-Q1 Other Parts Discussed in Thread: ADS7841 Hello Guys,
Good day.
I have a question specific to the chip itself (ADS7841). What is the expected output if channel input voltage is higher than Vref? It seems that the input…
Part Number: ADS7841 Hello,
I would like you to confirm about below.
* Could you please tell us allowable source(input) impedance ?
We would like to input voltage which is devided by resistor to CHx.
However, there is no spec about source impedance…
Part Number: ADS7841-Q1 Hi,
Can you explain more about the BUSY pin function of ADS7841-Q1? And how to utilize this signal?
Is it a must-have for SPI communication? As the MCU only support 4-wire SPI interface and there's no additional pin for BUSY…
Part Number: ADS7841 Tool/software: Linux Dear TI,
We are working on i.MX8QXP with ADS7841Q for one of the project. We connected the ADS7841Q to one of the spi bus of the processor. Here we couldn't find the driver for ADS7841. So we configured the…
