hello,i would like to know the range of supply voltage(max and min) for the next 2 AO,i attached the link for both AO,i don´t see clear in the datasheet those values:
The LF411CN min/max and differential voltage tollerance is clearly stated on page 3 of it's datasheet.
The TCA0372DP1 max differential and a note as to it's restrictions on input voltage is clearly stated on page 2 of it's datasheet.
What are you having trouble reading in the datasheet these values are very clearly stated. I would give the values directly but I think it would be more important to understand how you were not able to determine them for yourself. If I can help you understand how to read the datasheet it's be far better than the specific values in this case.
Please clarify exactly what problems you're having with reading the datasheet, specifically what part is confusing you.
The graph shows a knee at Vcc=+2V, Vee= -2V. So a a +4V supply centre-tapped to provide a virtual earth might work. But if the amp output can't swing below 1.3V won't that be a limitation?
i won´t need it with output lees than 1.3V, because i don´t know if you see that i am the same guy who is working with the pwm signal ,so the motor works between 1.5 and 3V
about the 411 os correct about the +-5V? or it is +5 ground
