Evaluates: MAX9736A/MAX9736B 19-4071 Rev 1 9/09 MAX9736A Evaluation Kit General Description Features The MAX9736A evaluation kit (EV kit) is a fully assembled 8V to 28V Single DC Power-Supply Operation and tested printed-circuit board (PCB) that configures Fully Differential Outputs the MAX9736A Class D amplifier to drive 2 x 15W into a pair of 8 speakers in stereo mode, or 1 x 30W into a Drives 2 x 15W into 8 Speakers in Stereo Mode 4 speaker in mono mode for audio applications. The Drives 1 x 30W into 4 Speaker in Mono Mode EV kit operates from an 8V to 28V DC power supply and is configured for +17.1dB gain. The MAX9736A EV Shutdown and Mute Control kit accepts a pair of single-ended input signals and Selectable Modulation Scheme provides two sets of differential outputs for speakers. The MAX9736A EV kit provides an option to control the Evaluates the MAX9736A/MAX9736B in 32-Pin shutdown, mute, modulation scheme, and mono mode TQFN-EP Package of the MAX9736A. The EV kit includes convenient audio Fully Assembled and Tested input and output connectors and the required output fil- ters to ease evaluation. The MAX9736A EV kit can also evaluate the MAX9736B after IC replacement (U1). Ordering Information PART TYPE MAX9736AEVKIT+ EV Kit +Denotes lead(Pb)-free and RoHS compliant.
