MAX9725E Evaluation Kit
General Description
The MAX9725E evaluation kit (EV kit) is a fully assem-
bled and tested printed-circuit board (PCB) that uses
the MAX9725E IC to drive a stereo headphone in
portable applications. The MAX9725E is a low-power
stereo headphone amplifier with adjustable gain and
DirectDrive? outputs. Maxim’s DirectDrive technology
eliminates the need for bulky DC-blocking capacitors at
the output of the amplifier.
The EV kit is configured for a -1.82V/V gain and is
designed to operate from a 0.9V to 1.8V DC power sup-
ply. The EV kit is capable of delivering up to 20mW per
channel into a 32 Ω load and achieves 0.006% THD+N.
The MAX9725E EV kit can also be used to evaluate the
MAX9725A, MAX9725B, MAX9725C, or MAX9725D
fixed-gain amplifiers. Contact Maxim for free samples of
the MAX9725A, MAX9725B, MAX9725C, or MAX9725D.
See the Part Selection Table for IC ordering information.
The MAX9725_ IC temperature range is -40°C to +85°C.
