The TLV1012 is an audio amplifier series for small-form-factor electret microphones. This two-wire amplifier is

designed to replace JFET amplifiers currently in use. The TLV1012 is ideally suited for applications that require

high signal integrity in the presence of ambient or RF noise, such as in cellular communications. The TLV1012

audio amplifier is specified for operation over a 2.2-V to 5-V supply voltage range with a fixed gain of 15.6 dB.

The device offers excellent THD, gain accuracy, and temperature stability compared to JFET microphones.

The TLV1012 enables a two-pin electret microphone solution, which provides direct pin-to-pin compatibility with

the existing JFET market.

The TLV1012 is offered in a space-saving four-terminal ultra-thin lead-free package (YDC) and is ideally suited

for the form factor of miniature electret microphone packages. The TLV1012 is characterized for operation over a

free-air temperature range of –40°C to 85°C.
