Mono 3.2W Class D Amplifier
with Integrated Input Coupling Capacitors
Maxim Integrated Products 1
General Description
The MAX98314 mono 3.2W Class D amplifier provides
Class AB audio performance with Class D efficiency.
This device offers five selectable gain settings (0dB,
3dB, 6dB, 9dB, and 12dB) set by a single gain-select
input (GAIN).
Active emissions limiting (AEL) edge rate and overshoot
control circuitry and a filterless spread-spectrum modu-
lation (SSM) scheme greatly reduce EMI and eliminate
the need for output filtering found in traditional Class D
devices.
The IC’s low 0.95mA at 3.7V, 1.2mA at 5.0V quiescent
current extends battery life in portable applications.
Highly linear, integrated input coupling capacitors (CIN)
reduce solution size and provide excellent THD+N, PSRR,
and CMRR performance at low frequencies vs. standard
Class D amplifiers using external input capacitors.
The IC is available in a small 9-bump, 0.3mm pitch WLP
(1.0mm x 1.0mm x 0.80mm) package and is specified
over the -40NC to +85NC extended temperature range.
