Part Number: TM4C1294NCPDT
Hello all,
First I foremost I want to say that I have reach out to the Digital Converter forum and I didn't receive much help over there and my problem is still going on. I've stuck for 3 days so I decided to come here and…
>>>1. What is absolute maximum ratings of Vref?
VREF being an analog pin can tolerate -0.3V to (VCC + 0.3V )(per the Absolute Maximum Ratings).
>>>2. If Vref is larger than Vcc, how Vin (differential, full-scale) range is?
Vref larger than Vcc is…
Hello Alex,
You are sending the sequence. This device allows for the negative pin to be set above or below ground, (-0.2V to 1.25V) as you have noted, this is primality to help with common noise. This device though is older and back at that time, the…
Other Parts Discussed in Thread: ADS7841 Dear all,
Please find below a question from my customer, could you please clarify the concerns ?
We have an offset of 155 mV in the ADS7841 we are using, please see table in my email below. According to TI…
Hello,
Please refer to TI Precision Labs - ADC link below
Building a simplified SAR ADC model and input driver is discussed in Section 5.
I have enclosed here a simplified TINA model for ADS7841 made on the steps explained in Precision Labs material…
Other Parts Discussed in Thread: ADS7841 Hello,
Our customer use the ADS7841.
The BUSY pulse occur at after 8 clocks.
In sometime, it occur at after 11 clocks.
Is it correct?
The configuration of the customer as follows.
12bit conversion mode…
Hi Vishy
Thank you for your reply.

Here is the link for reference buffer driver circuit. This paper talks about composite buffer architecture which is required for higher precision ADCs (16 bit and above)
For ADS7841 (12 bit resolution), driving reference pin through good…
Other Parts Discussed in Thread: ADS7841 Hi
According to the Figure 1 on the datasheet of ADS7841, there are two capacitors at +VCC, 0.1uF and 1uF to 10uF.
The capacitor that is 1uF to 10uF would be electrolytic capacitor.
What is the purpose…
