Part Number: ADS7865 Hi, The datasheet for the ADS7865 specify a minimum fCLK of 1MHz. Is this just due to the sample and hold stage (self discharge of Cs) or is the converter not functional at all with a lower fCLK? The reason for this question is that…
Other Parts Discussed in Thread: ADS7865 , AMIC120 Hi Team, We would like to get your help with the suggestion to our customer for a processor that is capable to perform DSP operations on stored signals? The customer application is sensor signal sampling where…
Part Number: ADS7865 Other Parts Discussed in Thread: OPA2836 , OPA2301 , OPA2365 Hi all Would you mind if we ask ADS7865? How much is the internal parasitic capacitance? Our customer is worried about memory effect by changing channel at MUX. In order to prevent…
Part Number: ADS7865 Hi,
In the spec od ADS7865 it is stated that BVDD absolute maximum rating is 1.5 x AVDD. Is this demand valid also during voltage shut down to the device, or only during nominal operation?
Thanks,
Eli.
Part Number: ADS7865 Hi all Would you mind if we ask ADS7865? <Question1> How much is the recommended the value of capacitance at input pin? Is our following recognition correct? The capacitor in the RC kickback filter is typically selected to be >10…
Part Number: ADS7865 Hi all Would you mind if we ask ADS7865? Could you let us know the relationship between AVDD and REFIN. -Analog inputs are single end. -REFIN is sapplied by external referecence voltage. The customer doesn't use REFOUT. In case of follows…
Part Number: TMS320C28346 Other Parts Discussed in Thread: ADS7865 Hi, i'm using the adc ADS7865 interfaced with the XINTF peripheral at TMS320C28346. I checked with the oscilloscope the handshaking line and the timing is corret. In particular I have…
Part Number: ADS7865 Hi all Would you mind if we ask ADS7865? <Question> On the layout on the datasheet P26 Figure 37. Optimized Layout Recommendation, it seems that 22pin(WR) connects to BVDD. It is mistake between 22pin(WR) and 24pin(BVDD), right? 22…
Other Parts Discussed in Thread: ADS7865 Hi all Would you mind if we ask ADS7865? Our customer will use VREFOUT for REFin. On P4 ELECTRICAL CHARACTERISTICS, Reference output voltage is from 2.485V to 2.515V with DAC = 0x3FF and –40°C < TA < +125°C.…
