Dear Team,
Please suggest Amplifier which amplifies 5uV input differential voltage.
Input Range : 5μV‐ 10mV
I need to confirm my design , Does INA166 supports my input range of operation.
Regards,
Rohith K
Hi Vikas,
Using the INA166, you'll need to convert the current/charge output of the hydrophone back to a voltage to be amplified. For this application, a simple resistor across the hydrophone outputs (that is, between the two inputs of the instrumentation…
Part Number: INA166 Hello,
This is my first post to the E2E forum.
I'm looking for a way to high-gain amplify the audio signal from a MEMS microphone. I'm presently using SPW2430 MEMS mic on this breakout board for testing, but wish to eventually…
Part Number: INA849 Other Parts Discussed in Thread: OPA1662 , , INA851 , INA163 , INA166 Hi,
I am having problems with an INA849 amplifier circuit. The input is intended to interface to an un-amplified dynamic 5 Ohm microphone with a 250uVrms output…
Hi Eggsy,
I would recommend to have two stage amplification for the the application, sine BW is up to 300kHz and Gain =600.
1. Connect the differential input signal to INA128, INA826, INA188, INA166 etc. instrumentation amplifier, say set the gain…
Other Parts Discussed in Thread: RC4580 , LM833 "Balanced" Mic Pre-Amplifier (PGA2500/INA166?)
Q:
1. Can "bipolar" input and "balanced" be thought of as the same thing?
2. What follow up will I need to narrow down which pre amp is best?
A: …
Shelly,
This is not the correct forum for audio ADCs and DACs. However, the amplifiers that are specifically intended for microphone pre-amplifier use are the: INA217, INA163, INA166, and the older INA103. The typical microphone pre-amplifier circuit…
Nathan,
Two additional parts to consider are the INA163 or INA166. These parts are intended to be used with low impedance transducers, such as microphones, and therefore sacrifice input bias current for lower noise and wider bandwidth. The INA166,…

Other Parts Discussed in Thread: INA103 , INA166 , OPA1641 , OPA376 Hi,
I've got a high impedance (3-10pF), low noise(<140dBV at 1Khz) microphone that I would like to pair with a high gain amp. Looking through the TI-Burr Brown pages I come across…
