General Description

The MAX13331 evaluation kit (EV kit) is a fully assem-

bled and tested surface-mount circuit board that evalu-

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.

The MAX13331 EV kit can also evaluate the MAX13330

IC. This requires the IC replacement of U1.

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

♦ Ultra-Compact Solution

♦ Low-Profile (1.2mm, max) Design

♦ Lead(Pb)-Free and RoHS Compliant

♦ Fully Assembled and Tested Surface-Mount Board
