Shugz End Product Extended Mix Mp3 Portable Devices SuchThe MAX9850 is designed to meet the board space and performance requirements of portable devices such as cell phones and MP3 and portable DVD players. The MAX9850 uses Maxims DirectDrive headphone technology that produces a ground-biased analog audio output from a single supply, which allows for driving the headphones directly from the amplifier outputs without large DC-blocking capacitors. This feature saves board space, provides higher clickpop suppression, and improves low-frequency (bass) response. The architecture does not require the headphone jack to be biased to a DC voltage and thus allows for a conventional, grounded chassis design. The MAX9850s flexible clocking circuitry utilizes any available system clock up to 40MHz, eliminating the need for an external PLL and multiple crystal oscillators. The DAC supports a wide range of sample rates from 8kHz to 48kHz in both master and slave modes, making the MAX9850 the easiest to use and most versatile audio DAC available. It can also be operated like traditional synchronous DACs, at any integer-oversampling ratio. The audio DAC receives input data over a flexible 3-wire interface that supports left-justified, right-justified audio data, or IS-compatible audio data. Stereo audio line inputs are provided to either mix analog audio with the digital input stream, or to drive the headphone outputs directly. Mode settings, headphone amplifier volume controls, and shutdown for both the headphone and line outputs are programmed through a 2-wire, IC-compatible interface. All Hardware Development Design Tool Simulation CADCAE Symbols Hardware Development Evaluation Board MAX9850EVCMOD2 Data Sheet 50.00 Buy Now Description The MAX9850 evaluation system (EV system) consists of a MAX9850 evaluation kit (EV kit), a companion Maxim command module (CMOD232) interface board, and software. The MAX9850 EV kit is a fully assembled and tested surface-mount printed circuit board (PCB) that evaluates the MAX9850 headphone stereo DAC with integrated headphone driver. The EV kit is designed to be driven by any digital audio SonyPhilips Digital Interface (SPDIF) audio source and can be optionally configured to accept generic digital audio or IS-compatible signals. The EV kit provides RCA jacks for connecting analog input signals. A 3.5mm headphone jack allows for easy connection of headphones to the PCB. ![]() The program is menu driven and offers a graphical user interface (GUI) with control buttons and a status display. The MAX9850 EV system (MAX9850EVCMOD2) includes both the EV kit and the CMOD232 interface board. Order the MAX9850 EV kit (MAX9850EVKIT) if you already have a command module interface.
