Part Number: ADS7853 Other Parts Discussed in Thread: ADS7253 , Hi,
Before,ADS7253 is used in mass production products.
Now we use ADS7853 to replace ADS7253 with only change the SPI's protocol,
and sampling accuracy becomes worse.
Part Number: ADS7853 Hi Experts,
Good day. We have this query from Cx (he is using free email):
ADS7853: 14 Bits, 1 MSPS, but I am only receiving a 1kbps sampling rate when reading via SPI, do you have any advice on what could be the bottleneck? Do I…
Part Number: ADS7850 Other Parts Discussed in Thread: ADS7853 Hi team,
need to replace ADS7850 with ADS7853. Does ADS7853 device can be fully compatible with ADS7850 on power up without writing data to control register?
Part Number: ADS7853 Hi,
as mentioned in the datasheet of ADS7853 figure 90., to read back the configuration register (CFR) you have to use 48 SPI clocks. As it is easier for our system to integrate we would just want to use 32 SPI clock sequences, but…
Part Number: ADS7853 Dear colleague,
Our customer plan to use ADS7853 in 1MHz sample rate, the clock frequency is 33.3333MHz, the clock period is 30ns.
But in datasheet as below, tclk MIN is 29.4ns, 30ns is very close to 29.4ns, is that a problem?
Part Number: ADS7853 Other Parts Discussed in Thread: MSP430F249 , I'm using an ADS7853 with an MSP430F249, and I seem to get an extra frame when I talk to it. I am running the ADS7853 in 16-CLK Dual SDO Mode with 16 CLK cycles per frame, however after…
Yes, apologies for such a long response time! The issue was related to three things; first I was sending 8 less clocks than I needed to (40 vs 48) on the first frame. The second issue was related to hardware; I had a bad wire between my MSP430…
Part Number: ADS7853 dear
ADS7853 has two SDO_A and SDO_B,if l use channel A ,what should l do to SDO_B, connect to gnd or just leave nc？
my input is single-ended,l just use one channel , what should I do to the unused channel? connect to gnd or just…
After looking at the ADS8353 I don't think a native SPI mode(either the SPI or the McBSP in SPI mode) will get what we want, due to the clocking requirement and relationship to CS signal. I think the control of the CS needs to be handled…
Part Number: ADS7853 Hi,
my customer is currently working on a design with ADS7853 and they have a concern.
First they set the configuration register for 16-bit mode, 2 data lines, etc Data: “1000_1010_0001_0000”
Clock frequency is 2.5 MHz…
