Hi Tom,
Apologies for bothering you again but just want to confirm that will the following connections for ADS7945 work for the device which will go into production without any risk of failure due to these connections?
Signals when analog supply is off…
Part Number: ADS7945 Hi,
I have some questions.
1. Channel Selection
CH SEL can be toggled at any time during the window specified in Figure 77 of datasheet.
But TI recommend to select the desired channel after the first SCLK rising edge and before…
Hi Collin,
I an sorry that I cannot understand fully of your saying.
the result is that i should find another IC instead of ADS7945?
then what is the suitable IC for our purpose? would you recommend for me?
Best regards,

Part Number: ADS7945 Hi team,
Looking at the DEVICE OPERATION of 16-clock mode in the datasheet, SDO is kept LOW durind 15 and 16 cycle of SCLK. However, customer found that SDO is pulled HIGH at 16 cycle of SCLK. Is this a correct behavior?
SDO was…

Hi, we are using ADS7945 adc and thinking of using THS4531 fda with it. While going through datasheet I came across some things I didn't understand.
1. what is the range of input differential…
Part Number: ADS7945 Hi support team,
I have a question regarding PCB layout of ADS7945 . It is recommended in the datasheet of ADS7945 that a spilt ground plane for analog and digital enables better results.
And the ADS7945 ground pins are connected to…
Part Number: ADS7945EVM-PDK Other Parts Discussed in Thread: ADCPRO , ADS1298 Tool/software: WEBENCH® Design Tools Hello,
I'm using ADCPro v 2.0.1 build 4 and EVM ADS794xEVM v2.0.0.0 with ADS794xEVM-PDK.
I have installed both applications and connected…
Part Number: ADS7945 Other Parts Discussed in Thread: ADS9110 , ADS9224R , ADS9234R , The transistion noise spec is 25uV which is approx .04LSBs. This seems remarkably low for a 2MSPS 14bit convertor - it is better than many (most?) 18 bit converters such…
Part Number: ADS7945 Hi support team,
I have a question regarding unused analog input terminals of ADS7945.
If the customer doesn't use a pair of analog input terminals (AINxP, AINxN), can he left them open? Or is it necessary to take measures such…
