Other Parts Discussed in Thread: ADS1675, TMUX6119, OPA211
Hello all,
I am working in a design with the above reference. Due to the lack of experience in the analogi world I have a doubt on how I should suppy the input to the ADC
My input is a 0-10V coming from an analog sensor.
In my understanding the ADC range is +-3.78V for VREF=3V (pag 17).
According to the datasheet the analog inputs must be driven differentially to achieve optimun performance and two examples are given for single ended and differential signals (Fig.10 and 11).
So my Input signal is unipolar and single ended but I need to transform it to a singled ended bipolar to get into the driver circuit (Fig 10, single ended input recommended circuit).
My question are:
- how I can modify my input to get into the driver circuit? any application note? what should I do?
- On the other hand, there is not any EVM board available for ADS1605 (maybe is obsolete) , is there any way to get one?
Thanks in advance.
Joaquín.
