Description
LMV1032-06/LMV1032-15/LMV1032-25 Amplifiers for 3 Wire Analog Electret Microphones February 2004 LMV1032-06/LMV1032-15/LMV1032-25 Amplifiers for 3 W.
The LMV1032 is an audio amplifier series for small form factor electret microphones.
Features
* (Typical LMV1032-06, 1.7V Supply; Unless Otherwise Noted) n Output voltage noise (A-weighted)
* 97 dBV n Low supply current 60 µA n Supply voltage 1.7V to 5V n PSRR 84 dB n Signal to noise ratio 58 dB n Input capacitance 2 pF > 100 MΩ n Input impedance < 200Ω n Output impedance n Max input si
Applications
* such as a bluetooth communication link. The addition of a third pin in electret microphones that incorporate the LMV1032 allows for a dramatic reduction in supply current as compared to the JFET equipped electret microphone. Microphone supply current is thus reduced to 60 µA, assuring longer batter
