AD605: Noise vs gain

GenevaCooper

Q
The noise figure f( Vgn) is given for a 20dB/V scaling ( cf page 5 of the DS
). What will it be for a 40dB/V ??

A
I don't have any measured results to give you, but the basic idea is that the
AD605 has roughly constant output noise…

AD605 PGA in ultrasonic flow meter

GenevaCooper

Q

I see quite large input impedance variation specified in the datasheet. Now I
wonder, is the input impedance varying with the gain? Or is it just varying per
device and constant over gain? This is important for my design because I need
to keep…

AD604 vs AD605

GenevaCooper

Q
The main difference between AD 604 and AD 605 is a preamplifier at the input
for the first one. This amplifier has very low noise : 0.7 nV/square(Hz). I
would like to find such a good amplifier. Which reference is it?

A
The low noise…

AD604 / AD605 : group delay and channel to channel phase variance

GenevaCooper

Q
Do you have any information as to the variation in phase between the two
channels of the AD605 as the gain is changed?

A
We have no phase information for the AD605, but we do have some group-delay
bench data for the AD604. The AD604…

AD605&AD8332 overshoot

project

Hi.Our team is developing new products on ultrasonic testing. We chose AD605 as the receiver VGA chip. However, we met a problem as the picture shows: Ultrasonic pulse would make the receiver overshoot although we have designer protection circuit before…

Hi.I am designing ultrasonic testing equipment. Take AD605 as the receiver. But when I connect the ultrasound probe(matching with inductor), I find that there are reverberation and almost 5us blind area on oscilloscope.Anyone can help me fix this？

RE: AD605 , AD8331 VGA Low frequency noise

bslimanea

We want to use the ad605 in a tympanometer project (medical purposes). Because it’s our first time to use AGC amplifiers, we find hard to make it work properly.
Indeed, a signal of 226 Hz going to be amplified and applied to a loudspeaker. A microphone…
