MAX9892 Evaluation Kit
Evluates:MAX892
General Description
Features
The MAX9892 evaluation kit (EV kit) is an assembled
and tested PCB that evaluates the MAX9892 IC.
The MAX9892 is an audio click-and-pop eliminator IC.
The EV kit circuit includes an on-board MAX4338 head-
phone amplifier, two RCA audio input jacks, and a
headphone jack to demonstrate the performance of the
MAX9892. The EV kit operates from a 2.7V to 5.5V DC
power supply.
o 2.7V to 5.5V DC Single-Supply Operation (On-
Board Headphone Amplifier)
o 1.7V to 5.5V DC Single-Supply Operation (External
Headphone Amplifier)
o Proven Audio PCB Layout
o On-Board MAX4338 Headphone Amplifier
o RCA Audio Input Jacks
The MAX9892 EV kit can also eliminate the audible
clicks and pops of an external headphone amplifier
connected to the EV kit. When utilizing an external
headphone amplifier, the MAX9892 EV kit can operate
from a lower input-voltage range of 1.7V to 5.5V DC.
o Headphone Output Jack
o PCB Pads for Audio Input and Output Signals
o Evaluates the MAX9892ERT+ in a 6-Bump UCSP™
(2 x 3 Array) Package
o Lead(Pb)-Free and RoHS Compliant
o Fully Assembled and Tested
