Hi Paul,
Since the idea behind the LMV1012 is to replace the JFET already inside the ECM (Electret Condenser Microphone), and the challenges of keeping the device as close to the microphone as possible, it is assumed that the ECM itself will be used…
Other Parts Discussed in Thread: ADS803 , LMV1012 Hi,
I am using a MEMS Microphone ADMP504 whose output is to be fed to a 12 bit ADC.
ADC i have chose is ADS803.
This ADC has an input capacitance of 20pF (Typical).
Since the MIC's output…
Part Number: TLV9361 Other Parts Discussed in Thread: LMV1012 , , OPA375 , LP2982 Tool/software: Hi, Ti.
I constructed an electret microphone amplification circuit using LMV1012 and TLV9361.
When I designed a circuit with a single 3.7V battery and…
Part Number: TLV320ADC3120 Hi expert,
Following the thread LMV1012: Questions , customer prefer to have PDM data stream like FAN3852 so having minimum effort of changing FW. Does TLV320ADC3120 support PDM or could you please advise any others?
Regards…
Part Number: OPA375 Other Parts Discussed in Thread: LMV1012
Hi, Ti.
I constructed an electret microphone amplification circuit using LMV1012 and OPA375.
The schematic is below.
I want to connect this circuit to a Bluetooth module(BM20…
Other Parts Discussed in Thread: PCM9211 , LMV1012 Hello,
I'm looking for a simple solution to convert microphone audio to S/PDIF stream.
Does TI have products in its portfolio to achieve this functionality?
Thanks.
Pavel.
Hello citizen,
A search of TI.com did not yield any similar TI products to the FAN3852. There is the LMV1012 microphone preamp, but its doesn't have a built-n A/D function.

Hello Mahendra,
You may take a look to the LMV1012 or LMV1032, these are specialized amplifiers for small form factor electret microphones.

Hello Rudy
Welcome to E2E, thanks for your interest in our products.
As you have mentioned one solution is to design the circuit yourself, but I'd recommend you to have a look to the LMV1012 and LMV1032, you could use them in the first stage of the…
Jota, You're right the preamp should be powered, this is why phantom power is required. You can see this preamp as a LMV1012, the pull up resistor at the output is the phantom power. You can then connect this output (through the coupling capacitor) to…
