... Differential Microphone Preamplifiers with Internal Bias and Complete Shutdown Fixed Differential Gain (MAX4060) The MAX4060 has an internal fixed gain of 10V/V for its differential input. This feature simplifies design, reduces pin count, footprint, and eliminates external gain-setting resistors. Adjustable Differential-Gain Setting The MAX4061/MAX4062 allow the user to alter the gain to optimize the signal-to-noise ratio (SNR) of their sys- tem ...

... Differential Microphone Preamplifiers with Internal Bias and Complete Shutdown MICROPHONE INPUT Figure 2. MAX4060 Used for Biasing a Microphone The MAX4061/MAX4062 have a lower bias voltage and low-impedance outputs (optimum electret bias resistor can then be set externally). This gives a low-noise, flexi- ble solution that can run from 2.4V to 5.5V, suitable for hand-held devices such as PDAs that typically have audio power supplies in the 3V region (see Figure 3) ...
