MAX13331 Evaluation Kit
Evluates:0/MAX31
General Description
Features
♦ No DC-Blocking Capacitors Required
♦ 4V to 5.5V Single-Supply Operation
♦ Adjustable Gain (MAX13331 Only)
♦ 125mW Per Channel into 32Ω at 0.01% THD+N
♦ Shutdown Control
The MAX13331 evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount circuit board that evalu-
ates the MAX13331 DirectDrive® stereo headphone
amplifier. DirectDrive eliminates the two large DC-
blocking capacitors typically required between the out-
put of the amplifier and the headphones. The
MAX13331 EV kit includes two RCA phono jacks on the
input and a 3.5mm headphone jack on the output to
facilitate easy connections to the circuit board.
♦ Ultra-Compact Solution
The MAX13331 EV kit can also evaluate the MAX13330
IC. This requires the IC replacement of U1.
♦ Low-Profile (1.2mm, max) Design
♦ Lead(Pb)-Free and RoHS Compliant
♦ Fully Assembled and Tested Surface-Mount Board
