Looking for Pre amp for our microphone (ECM) application.
The TLV1012,a low cost solution look interest, but it seems to be used only inside a microphones.
Is it correct,?can it be used with d/a?

Hi, Eli,
Let me see if I can round up someone on this...

Eli,
The TLV1012 has no VCC pin, the output and VCC are the same pin. This is ideal for a two wire microphone cable.
However, it can be used outside a microphone to amplify audio signals.

Eli,
Yes, it can amplify a microphone signal with the output connected to a D/A.
Hi Ron,
We're using the TLV 1012 as a pre amplifier for our MIC input. We're facing a specific noise coupled to Pre amplifier output whenever Wi-fi enabled. In data sheet , it has suggested to connect 10pf & 33pf on Pre amplifier o/p for avoiding noise due to GSM signal (980, 1800/1900 MHz). Similarly can i use some capacitor to avoid Wi-fi specific noise (2400 MHz)? what should be the capacitor value? can you please guide me on this issue?
Thanks & regards,
