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. So…
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 spidev…
Part Number: ADS7841-Q1 Other Parts Discussed in Thread: ADS7841 Hi
Our customer has questions about ADS7841-Q1.
Can you give us your expertise?
1.
What is absolute maximum ratings of Vref?
2.
If Vref is larger than Vcc, how Vin (differential, full…
Part Number: ADS7841-Q1 Other Parts Discussed in Thread: ADS7841 Hi
The following waveform is obtained by customer.
Could you please check it and tell us your view?
① You can see glitch on DIN. It should be generated by host.
It doesn’t cross DCLK…
Part Number: ADS7841-Q1 Other Parts Discussed in Thread: ADS7841 Hi
I'm referring SBAA178.
I want to have value for C_ESD, R_SW and C_SH of ADS7841-Q1.
C_IN can be referred in datasheet as C_IN = 25pF(typ) over temperature range.
Can you offe…
Part Number: ADS7841-Q1 Hi,
I am checking whether the IC may not operate properly depending on the instant of power supply interruption time and the value of power supply voltage. The figure below is an image. Are there any conditions that cause problems…

Part Number: ADS7841-Q1 Other Parts Discussed in Thread: ADS7818 Hi
I can see the datasheet says DCLK HIGH/LOW time is 150ns (min) from the TABLE VII.
Is there any other constraint for DCLK? (such as Duty cycle)
1. Do you have maximum time of DCLK …
Part Number: ADS7841-Q1 Hi
According to the datasheet, ADS7841-Q1 seems to have clump diode to VCC at input channel (CH0-CH3) because its Vin (analog in) is restricted by VCC+0.3V as absolute maximum ratings.
So, the analog Vin(max) must be limited by…

Hi
1.
We want a graph that shows Supply Current vs Temperature at VCC=5V. We can see the one of VCC=2.7V, but VCC=5V is not on the datasheet.
Do you have it?
2.
According to the datasheet, Iq(max) is 650uA at VCC=2.7V as the…
