MAX5406 Audio Processor Preamplifier Projects

MAX5406 The proposed preamplifier is imposing several requirements. The preamp must allow volume control and balance (distribution of volume between channels), then it must allow the correction of the frequency characteristics. These requirements are satisfied by a number of integrated circuits intended for realization of the lna. These circuits, in all cases using to control the potentiometers. For the realization was chosen the circuit allows more elegant control with the buttons. This circuit is audioprocesor company Maxim MAX5406

Digital Preamplifier Circuit MAX5406

Circuit MAX5406 is audioprocesorem controlled using the buttons. Has 32 stepper potentiometer for volume management, allows the correction of low and high frequencies (lows and highs) in 21 steps, contains the function of the mute (muting the volume) and “ambience” (special effect editing sound outside-vented). The circuit is manufactured in two types of cases with 48 pins. This is the case 48 TSSOP and 48 TQFN-cases are designed for surface mounting. To implement it selected case 48 TSSOP. Audioprocesor allows connection of a symmetric or asymmetric signal. The circuit is equipped with inputs for connection of two stereo signals, which are to be aggregated. Output the signal is in the form of asymmetric stereo signal. There is also output for active subwoofer, whose signal is not úrovňově influenced by, is the only frequency limited
