Part Number: ADS7844 The ADS7844 datasheet specifies absolute maximum input voltage for analog inputs (multiplexer inputs and reference input) is "-0.3V to +Vcc + 0.3V". Do ADS7844 analog inputs have ESD protection diodes? If so, can absolute maximum…
Part Number: ADS7844 Hi Dear,
The customer has selected ADS7844 and wants to accelerate the software development process. Is there a driver routine based on ARM platform that can be provided to the customer for reference? thanks
Part Number: ADS7844 A few ADS7844 board are not output for BUSY and DOUT.
Waveform is attached below;
※Red: SCLK, Yellow: DIN, Write: BUSY, Blue: DOUT, 10μs/div
Please let me know about two points below;
・Is there any problem on above waveform? …
Part Number: ADS7844 Hi Team,
We have some questions for the SPI behavior during working with the customer. The waveform below is capture from the ADS7844 SPI bus.
We noticed the waveform is changing state on different edge of the clock signal (red…
Part Number: ADS7844 Hi team,
My customer is looking to work with the ADS7844 and are curious if there is an maximum source impedance. Do we have a maximum source impedance spec for the ADS7844?
I found a similar question in another E2E forum post, but…
Part Number: ADS7844 Hello,
My customer is using the ADS7844, can you help to clarify below question?
1. After control byte is completed, When does the busy signal go low if no DCLK never?
2. what is the BUSY signal status after control byte is completed…
Part Number: ADS7844 Hi,
In the datasheet for the ADS7844, the absolute maximum input voltage rating for the analog inputs is given as -0.3 V to VCC + 0.3 V. However, in the specification table, an "absolute input range" for the negative inputs (when…
Part Number: ADS7844 Other Parts Discussed in Thread: REF3425
The 32-channel voltage acquisition circuit uses 4 ADS7844. Can I share a REF3425 reference? If not, how can I handle it?
Part Number: ADS7953 Other Parts Discussed in Thread: ADS7844 Hi Team, Our customer wanted to change their ADS7844E/2K5 to a 16-channel variety and found ADS7953 as an option. They would like to confirm if the drivers of ADS7953 is compatible with ADS7844E…
Part Number: ADS7844 I'm attempting to use the 24 clock cycle model to communicate with the device (Figure 3 in user's manual) but I never seem to get any data back from the device during the 16 clock cycles "Conversion". I do however…
