Lmv1031ur 20 Amplifier - China

price: check with company for price

The LMV1031 audio amplifier is an ideal replacement for the JFET preamplifier that is currently used in the electret micro- phones. The LMV1031 is optimized for applications that require extended battery life, such as Bluetooth communication links. The supply current for the LMV1031 is only 72 µA.
This is a dramatic reduction from that required for a JFET equipped microphone. The LMV1031, with its separate out-
put and supply pins, offers a higher PSRR and eliminates the need for additional external components.
The LMV1031 is guaranteed to operate from 2V to 5V supply voltage over the full temperature range, has a fixed voltage gain of 20 dB and enhanced SNR performance. The LMV1031 is optimized for an output biasing of 1.09V. The LMV1031 has less than 200Ω of output impedance over the full audio bandwidth. The gain response of the LMV1031 is flat within the audio band and is stable over the tempera-ture range.The LMV1031 is available in a large dome 4-bump ultra thin micro SMD package that can easily fit on the PCB inside the miniature microphone metal can (package). This package is designed for microphone PCBs requiring 1 kg adhesion criteria. If you want to know more about it, WELCOME to our website!
