Part Details:

19-3817; Rev 0; 5/06 Audio Processor with Pushbutton Interface MAX5406 General Description Features The MAX5406 stereo audio processor provides a com- Audio Processor Including All Op Amps and Pots plete audio solution with volume, balance, bass, and for Volume, Balance, Mute, Bass, Treble, treble controls. It features dual 32-tap logarithmic Ambience, Pseudostereo, and Subwoofer potentiometers for volume control, dual potentiometersfor balance control, and linear digital potentiometers for 32-Tap Volume Control (2dB Steps) tone control. A simple debounced pushbutton interface Small, 7mm x 7mm, 48-Pin TQFN and 48-Pin controls all functions. The MAX5406 advances the TSSOP Packages wiper setting once per button push. Maxim s propri-etary SmartWiperTM control eliminates the need for a Single +2.7V to +5.5V or Dual ±2.7V Supply microcontroller (µC) to increase the wiper transition Operation rate. Holding the control input low for more than 1s Clickless Switching and Control advances the wiper at a rate of 4Hz for 4s and 16Hzthereafter. An integrated click/pop suppression feature Mute Function to < -90dB (typ) eliminates the audible noise generated by the wiper s movements. Channel Isolation > -70dB (typ) The MAX5406 provides a subwoofer output that inter- Two Sets of Single-Ended or Differential Stereo nally combines the left and right channels. An external Inputs Can Be Used for Summing/Mixing filter capacitor allows for a customized cut-off frequen- Debounced Pushbutton Interface Works with cy for the subwoofer output. A bass-boost mode Momentary Contact Switches or Microprocessors enhances the low-frequency response of the left andright channels. An integrated bias amplifier generates (µPs) the required (VDD + VSS) / 2 bias voltage, eliminating Low 0.2µA (typ) Shutdown Supply Current the need for external op amps for unipolar operation. Shutdown Stores All Control Settings The MAX5406 also features ambience control toenhance the separation of the left- and right-channel 0.02% (typ) THD into 10k Load, 25µVRMS (typ) outputs for headphones and desktop speakers sys- Output Noise tems, and a pseudostereo feature that approximates Internally Generated 1/2 Full-Scale Bias Voltage stereo sound from a monophonic signal. for Single-Ended Applications The MAX5406 is available in a 7mm x 7mm, 48-pin TQFN package and in a 48-pin TSSOP package and is Power-On Volume Setting to -20dB
