    Module firmware. It does not pass through the HCI protocol layer. Hardware on ABM-400-Mxxx allows the data to be sent to the received from a SCO connection.

  • Page 10: Microphone Input

    Bluetooth™ Module Application Note 13.3 Audio Input Stage The input stage of ABM-400-Mxxx consists of a low noise input amplifier, which receives its analogue input signal from pins AUDIO_IN_P_LEFT and AUDIO_IN_N_LEFT to a second- order ADC that outputs a 4MBit/sec single-bit stream into the digital circuitry. The input can be configured to be either single ended or fully differential.

  • Page 11: Line Input

    Bluetooth™ Module Application Note 13.3.2 Line Input If the input gain is set to less than 21dB ABM-400-Mxxx automatically selects line input mode. In this mode the input impedance at AUDIO_IN_N_LEFT, AUDIO_IN_P_LEFT, UDIO_IN_N_RIGHT and AUDIO_IN_P_RIGHT are increased to 130kΩ typically. In line- input mode, the full-scale input signal is about 400mV rms.

  • Page 12: Output Stage

    1MHz. It uses its high open loop gain in the closed loop application circuit to achieve low distortion while operating with low standing current. Copyright © 2005 AirLogic Co., Ltd.
