The TLV1018 is ideal for extended battery-life applications, such as a Bluetooth™ munication link. The addition of a third pin to an electret microphone that incorporates a TLV1018 allows for a dramatic reduction in supply current pared to a JFET-equipped electret microphone. Microphone supply current is reduced to 70 µA, assuring longer battery life. The TLV1018 is specified for supply voltages from 1.7 V to 5 V and has fixed voltage gains of 15 d B and 25 d B. It offers low output impedance over the voice bandwidth, excellent power supply rejection (PSRR), and stability over temperature. The TLV1018 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 TLV1018 is characterized for operation over a free-air temperature range of - 40°C to 85°C. - 40°C to 85°C AV 15 d B 25 d B ORDERING INFORMATION(1) PACKAGE (2) ORDERABLE PART NUMBER Nano Star™ WCSP (DSBGA) - YDC Reel of 3000 TLV1018-15YDCR TLV1018-25YDCR TOP-SIDE MARKING Y28 YW8 (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..
