Part Number: INA217 Hello,
I would like to make an audio microphone preamp using the INA217 but I need it to work for both balanced and unbalanced mic.
Do I have to make any modification on the typical schematic application or can it work for unbalanced…
Other Parts Discussed in Thread: INA217 , OPA2137 Hello,
I'm working on a pre-amplifier using the INA217, but I couldn't get a linear operation for Vout. I saw that I can use this op-amp as single supply, but I can't make that work. Any suggestion?…
Other Parts Discussed in Thread: INA217 Hello !
I'm trying to use the INA217 or current sense amplification. I was happy to find this part because of it's high bandwidth at 40dB gain, which is what I am looking for.
However, I noticed that feeding…
Other Parts Discussed in Thread: INA217 , OP27 , REF02 The page for the INA217 touts TINA but I cannot find a model for it in the software - is there a model available?
I did a bit of homework about summing resistances and transformer impedance reflections.
With a 600ohm:600 ohm 1:1 transformer the windings ratio is 1 !!
Nice! .. the square of 1 is 1.
So reflected impedance of an 800 ohm resistor on the secondary is 800…
Other Parts Discussed in Thread: INA217 , TL071 Hello everyone, I'm having problems with the combination of the two.
The electret mic is a Panasonic WM-62
My goal is to record audio speech at low frequencies ( up to about 4kHz ). I'm using the schematics…
Hi,
I have built a circuit using INA217 with NR3158 knowles microphone without the XLR connector, but its not working with INA217, i couldn't understand why ?
I am not using any phantom power as per the circuit in fig. 4 of the data sheet and also…
Other Parts Discussed in Thread: INA110 , INA217 , INA128 I have a circuit that I originally put together a couple of years ago and it seemed to work quite well. It is an amplifier for a low impedance sensing element (around 25 ohm) that puts out a very…
Tony Martin said:
It is possible to connect V+ to 5V and V- to 0V in order to be able to connect an INA217 directly to a microcontroller?
Do they necessarely have to be connected simmetrically (+V and -V)?
Thank you!!!
The rails don't have…
Part Number: LME49600 Other Parts Discussed in Thread: INA217 , LM4881 Hi,
I am using INA217 as the pre-amplifier followed by an attenuator that works as the volume control. I'd like to use a buffer after the attenuator and right before a summing amplifier…
