It has an analog and digital programmable gain stage so that it can be optimized for different microphones. See Figure 1-4. STEREO AUDIO CODEC INTERFACE SPK_L- The built-in CODEC uses a fully differential architecture in the analog signal path, which results in low noise sensitivity and good power supply rejection while effectively doubling the signal amplitude. It operates from a 1.5 V single power supply and uses a minimum of external components. See Figure 1-5.

The firmware can control both terminals, and the battery charger can set LED0. The terminals are open-drain outputs; therefore, the LED must be connected from a positive supply rail to the pad in series with a current limiting resistor. You should operate the LED pad (LED0 or LED1 pins) with a pad voltage below 0.5 V. In this case, the pad can be thought of as a resistor, RON. The resistance--together with the external series resistor--sets the current, ILED, in the LED. The current is also dependent on the external voltage, VDD, as shown in Figure 2-1. LED INTERFACE VDD LED Forward Voltage, VF |LED RLED LED0 or LED1 APPLICATIONS The LEDs can be used to indicate the module's connection status. Table 2-1 describes the LED functions. TABLE 2-1: Restore Factory Defaults with GPIO4 You should connect the GPIO4 pin to a switch, jumper, or resistor so it can be accessed. You can use this pin to reset the module to its factory default settings, which is critical in situations where the module has been misconfigured. To reset the module to the factory defaults, GPIO4 should be high on power-up and then toggle low, high, low, high with a 1 second wait between the transitions. www.rovingnetworks.com Resistor Voltage Drop, VR Pad Voltage, VPAD RON = 20 The following sections provide information on designing with the RN52 module, including restoring factory defaults, using the LED interface, minimizing radio interference, solder reflow profile, typical application, etc. 2.1 LED Interface FIGURE 2-1: MICROPHONE INPUT The RN52 audio input is intended for use from 1 A at 94 dB SPL to about 10 A at 94 dB SPL, which requires microphones with sensitivity between -40 and -60 dBV. MIC_BIAS requires a minimum load to maintain regulation. MIC_BIAS maintains regulation within 0.199 and 1.229 mA. Therefore, if you use a microphone with specifications below these limits, the microphone output must be pre-loaded with a large value resistor to ground. 2.0 2.2 STATUS LED FUNCTION LED Status Description LED0 and LED1 Flashing The RN52 module is discoverable. LED0 only Flashing The module is connected.
