The TLV1018 is an audio amplifier for small-form-factor electret microphones and is designed to replace the currently implemented JFET preamplifiers. The TLV1018 is ideal for extended battery-life applications, such as a Bluetooth™ communication link. The addition of a third pin to an electret microphone that incorporates a TLV1018 allows for a dramatic reduction in supply current compared 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 dB and 25 dB. 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
