Hello,
I have seen data sheet of it what does three pin mean here?

tr - Reset Pulse Width 100 nS min
trs - Reset to Strobe Delay 72 uS min
ts - Strobe Pulse Width 18 uS min
tss - Strobe to Strobe Delay 72 uS min
to - Output Settling Time 36 uS min (with Cload = 22 pF and Rload = 1 Mohm)

RESET

STROBE

clk

MSGEQ7

 

Hello,

From what datasheet does the information come from?
Is there no timing diagram given in that datasheet?

Bertus

 

From the datasheet:

STROBE - Channel selection pin
RESET - resets multiplexer
CLKIN - clock oscillator pin

tr - Reset Pulse Width 100 nS min

A pulse on the reset pin must be wider than 100ns.

trs - Reset to Strobe Delay 72 uS min

The time between RESET goes low and STROBE must be, at least, 72us.

ts - Strobe Pulse Width 18 uS min

A pulse on STROBE must be wider than 18us.

tss - Strobe to Strobe Delay 72 uS min

There must be 72us between each pulse on STROBE.

to - Output Settling Time 36 uS min (with Cload = 22 pF and Rload = 1 Mohm)

The time it takes for the output to settle to a valid state is 36us.

That funny looking thing with squiggly lines (above where those numbers are listed) is called a timing diagram. This timing diagram shows what those signals mean in relation to the input signals.

 

Hi,
it is MSGEQ7 the output of it i.e. Dc is feed to LM3914 ?
I have not used it in any of project. so, is that DC value Changes with freq response of Band.
and the LM3914 display digital on LEDs?
Actually, this project is meant for DJ or sound system back stage do you want to give any suggestion?
