Evaluates: MAX98400B 19-5505 Rev 0 9/10 MAX98400B Evaluation Kit General Description Features The MAX98400B evaluation kit (EV kit) configures the S 8V to 28V Single DC Power-Supply Operation MAX98400B Class D amplifier to drive 2x12W into a pair S Fully Differential Inputs and Outputs of 8I speakers in stereo mode for audio applications. S Drives 2x12W into 8I Speakers in Stereo Mode The EV kit operates from an 8V to 28V DC power supply. S Limiter Control The EV kit has a programmable gain and the jumper set- tings default to a +20.1dB gain. The EV kit accepts a pair S Thermal Foldback of single-ended or differential input signals and provides S Shutdown Control two sets of differential outputs for speakers. S Evaluates the MAX98400B in a 24-Pin TQFN The EV kit has two independent amplifier circuits, dem- Package with an Exposed Pad onstrating direct speaker driving (for low component S U1 Configured for Filterless Output count) and filtered output driving (for ease of evaluation). The EV kit comes with two MAX98400BETG+ devices S U2 Configured for Filtered Output installed. S Fully Assembled and Tested The EV kit provides an option to control the limiter, thermal foldback, input configuration, gain, and shut- down mode of the device. The EV kit includes convenient Ordering Information audio input and output connectors. PART TYPE MAX98400BEVKIT+ EV Kit +Denotes lead(Pb)-free and RoHS compliant.
