TLV1012

The TLV1012 is an audio amplifier series for small-form-factor electret microphones. This two-wire amplifier is designed to replace JFET amplifiers currently in use. The TLV1012 is ideally suited for applications that require high signal integrity in the presence of ambient or RF noise, such as in cellular communications. The TLV1012 audio amplifier is specified for operation over a 2.2-V to 5-V supply voltage range with a fixed gain of 15.6 dB.The device offers excellent THD, gain accuracy, and temperature stability compared to JFET microphones.

Features of the TLV1012 are:(1)Supply Voltage: 2 V to 5 V; (2)Supply Current: < 180 A; (3)Signal-to-Noise Ratio (A-Weighted): 60 dB; (4)Output Voltage Noise (A-Weighted): ? 89 dBV; (5)Total Harmonic Distortion: 0.013%; (6)Voltage Gain: 15.6 dB; (7)Cellular Phones; (8)Headsets; (9)Mobile Communications; (10)Automotive Accessories; (11)PDAs; (12)Accessory Microphone Products.

The absolute maximum ratings of the TLV1012 can be summarized as:(1)Supply voltage: 0.3 V to 5.5 V; (2)Input voltage: 0.3 V to 0.3 V; (3)Thermal impedance, junction to free air:230.47 ° C/W; (4)Operating free-air temperature range : 40 ° C to 85 ° C; (5)Storage temperature range: 65 ° C to 150 ° C.
