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 munications. 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 d B. The device offers excellent THD, gain accuracy, and temperature stability pared to JFET microphones. The TLV1012 enables a two-pin electret microphone solution, which provides direct pin-to-pin patibility 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. - 40°C to 85°C AV (2) 15.6 d B ORDERING INFORMATION(1) PACKAGE (3) ORDERABLE PART NUMBER Nano Star™ WCSP (DSBGA) - YDC Reel of 3000 TLV1012-15YDCR TOP-SIDE MARKING Y38 (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI web site at .ti..
