General Description
The MAX9718/MAX9719 differential input audio power
amplifiers are ideal for portable audio devices with
internal speakers. The differential input structure
improves noise rejection and provides common-mode
rejection. A bridge-tied load (BTL) architecture mini-
mizes external component count, while providing high-
quality, power audio amplification. The MAX9718 is a
single-channel amplifier while the MAX9719 is a dual-
channel amplifier for stereo systems. Both devices
deliver 1.4W continuous average power per channel to
a 4
Ω load with less than 1% THD+N while operating
from a single +5V supply. The devices are available as
adjustable gain amplifiers or with internally fixed gains
of 0dB, 3dB, and 6dB to reduce component count.
A shutdown input disables the bias generator and
amplifiers and reduces quiescent current consumption
to less than 100nA. The MAX9718 shutdown input can
be set as active high or active low. These devices fea-
ture Maxim’s comprehensive click-and-pop suppres-
sion circuitry that reduces audible clicks and pops
during startup and shutdown.
The MAX9718 is pin compatible with the LM4895,
and is available in 9-bump UCSP, 10-pin TDFN, and
10-pin μMAX packages. The MAX9719 is available in
16-pin TQFN, 16-pin TSSOP, and 16-bump UCSP pack-
ages. Both devices operate over the -40°C to +85°C
extended temperature range.
