Part Number: ADS7853 Tool/software:
Hi team,
My customer want to invite you to check attached schematic layout for ADS7853. Do you have any advise whether this is good for them?
Part Number: ADS7853 Hello,
I plan to multiplexed the SCLK, SDI and SDO_A signal with another SPI interface signals, I want to know whether the SCLK, SDI and SDO_A signals can be configured to HiZ when CS signal of the ASD7853 is disabled.
Thank you…
Part Number: ADS7853 Tool/software: I wish to configure the ADS7853 to take external reference voltage for data conversion. We have REF5025AIDRG4 as a reference voltage generator to give 2.5V to the pins REFIO_A & REFIO_B. The decoupling caps have also…
Part Number: ADS7853 Other Parts Discussed in Thread: LAUNCHXL-F280039C , SYSCONFIG I am having issues with configuring the CFR. I am using the LAUNCHXL-F280039C to program/configure. There is no library for ADS7853 unlike many other ADCs available from…
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.
What…
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,…
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…
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: 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?
Regards,
Rayna
Hey Tom,
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…
