Features (Typical LMV1012-15, 2.2V supply, RL = 2.2 k, C = 2.2 µF, VIN = 18 mVPP, unless otherwise specified) Supply voltage 2V - 5V Supply current <180 µA Signal to noise ratio (A-weighted) 60 dB Output voltage noise (A-weighted) -89 dBV Total harmonic distortion 0.09% Voltage gain LMV1012-07 7.8 dB LMV1012-15 15.6 dB LMV1012-20 20.9 dB LMV1012-25 23.8 dB Temperature range -40°C to 85°C Offered in 4-bump micro SMD packages Description The LMV1012 is an audio amplifier series for small form factor electret microphones. This 2-wire portfolio is designed to replace the JFET amplifier currently being used. The LMV1012 series is ideally suited for applications requiring high signal integrity in the presence of ambient or RF noise, such as in cellular communications. The LMV1012 audio amplifiers are guaranteed to operate over a 2.2V to 5.0V supply voltage range with fixed gains of 7.8 dB, 15.6 dB, 20.9 dB, and 23.8 dB. The devices offer excellent THD, gain accuracy and temperature stability as compared to a JFET microphone. The LMV1012 series enables a two-pin electret microphone solution, which provides direct pin-to-pin compatibility with the existing JFET market. The devices are offered in extremely thin space saving 4-bump micro SMD packages. The LMV1012XP is designed for 1.0 mm canisters and thicker ECM canisters. These extremely miniature packages are designed for electret condenser microphones (ECM) form factor. Applications • Cellular phones • Headsets • Mobile communications • Automotive accessories • PDAs • Accessory microphone products

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
