Part Number: ADS1299 Other Parts Discussed in Thread: INA217 , INA163 , INA118 , OPA2188 , OPA333 Hi,
I am interested in observing analog EEG signals on the scope.
1. Does ADS1299 dev board has the option to probe the signals after PGA?
2. If not, can you…
Part Number: DRV134 Other Parts Discussed in Thread: INA217 , TINA-TI Hai,
I am using DRV134 device as line driver in my audio bus application. The bus consists of two DRV134 devices with the outputs shorted together i.e +V0 of one device is shorted with…
Nicholas, I believe INA110, INA111, INA116, and INA128 have sufficient bandwidth in gain of 10 for your application while INA103, INA217, INA826 may have the required speed but may not be best suited for bridge application because of their relatively…
Hi Icy,
Regarding the preamplifier I think you could take a look at INA163 or INA217. You can find a typical application circuit for microphone preamplifier in its datasheets.
And for the headphone amplifier I think you could choose one of the TPA613xA2…
Hi dlh,
You could take a look at devices like INA217 and INA163, I think these are similar to 1580.
Regarding the reference design I will seek for similar documentation in our literature database.
Best regards,

Hi Patrizia,
Welcome to e2e
I think some instrumentation amplifiers like INA163 or INA217 could fit in here.
As you need to detect a specific frequency, using a lock in amplifier seems to be a good choice. Perhaps you could add some additional band-pass…

Dear,
I want to amplify signal for Shure 514B microphone placed 40 meters from amplifier. I'm going to use INA217 and DRV 134 but I don't sure if my design is correct. I don't need phantom power.…
Hi Patrizia,
You could use lower phantom power if you need to.
What do you mean by "use R1 to place 2 voltage at the microphone?"
I think there should be no problem if you use one power supply for phantom power and INA power. Is your power…
Hi Zain,
Welcome to E2E and thank you for your interest in our products!
The preamplifier selection could be based on your microphone specs. 2-wire, 3-wire, digital, etc.
LMV1012 is 2-wire mic preamp and LMV1032 is 3-wire mic preamp, both available…
Other Parts Discussed in Thread: INA217 , INA163 , LME49743 , INA103 , PGA2500 , PGA2505 I am working on a multichannel balanced audio input circuitry.
The balanced audio input should be universal to allow greatest input level flexibility.
It should support…
