Part Number: ADS8509 when I use AD8809 sample voltage around 0.1V to -0.1V,it will give me wong data,such as 5V.But when it samples other voltage,it can give me right data.The schematic is as same as datasheet ,input range is ±10V with trim。
Part Number: ADS8509 Dear Technical Support Team,
My system monitors BUSY signal.
I have a question about BUSY.
① Is BUSY signal output any case/ anytime while conversion(tconv) ?
If BUSY is not output case, could you share the situation? ② What is MIN…
Part Number: ADS8509 Hello,
Regarding to wait time of PWRD on ADS8509, my customer is asking a question..
(Question)
When device is changed to normal power from low power by PWRD pin, how long should it wait for next conversion start?
Regards,
Tao…
Part Number: ADS8509 Other Parts Discussed in Thread: ADS8681 , ADS8685 , ADS8689 Hi TI technical experts,
i met a problem when using ADS8905, it looks like crosstalk on the ADC input when the converter starting conversion or transfer data.
To debug this…
Part Number: ADS8509 I am using the discontinuous EXT clock in this application. The data sheet indicates that the data output is valid on either edge of the internal clock if the internal clock is used, but does not indicate which edge should be used…

we are using the ADS8509 with its internal clock, sendig its data via spi as master to the MPU (that is slave), initiated by…
Part Number: ADS8519 Other Parts Discussed in Thread: ADS8509
Hello,
I am considering jumping from ADS8509 to ADS8519 ADC. I would like to avoid as many changes as possible to the surrounding circuitry (including the ADS8509 +/-10V input range connections…
Part Number: ADS8509 Other Parts Discussed in Thread: ADS7805 Hello
ADS8509 datasheet(SLAS324C) says that 2.2uF tantalum for CAP, 2.2uF tantalum for REF and 10uF tantalum (+ 0.1uF ceramic) for VANA are required on P6.
Is it OK to use ceramic capacitances…
Part Number: ADS8509 Other Parts Discussed in Thread: REF5025 Hello,
I am trying to bias an ADS8509 to have an input range of -0.1 to +4.9V, or similar.
I thought I would achieve this by reducing the 33.2K resistor in figure 29's 0-5V section.
It…
