GENERAL DESCRIPTION
The
SSM2932
is a stereo headphone amplifier capable of
delivering 50 mW continuous output power per channel into
16 Ω
single-ended loads at the 1% THD + N threshold. The
stereo headphone drivers are highly efficient, true ground-
referenced Class-G technology.
The
SSM2932
incorporates a gain control pin that selects
between 0 dB and 6 dB. The ground-referenced output scheme
eliminates the need for large dc-blocking capacitors, reducing
system BOM cost and board area. The Class-G amplifier is
fine-tuned to maximize battery life, a critical task in portable
applications. The device maximizes battery life by modulating
the amplifier power supply rail to match the output demand
without consuming excessive supply current, thus reducing
power dissipation during typical audio playback.
The
SSM2932
is specified over the industrial temperature range
(−40
°
C to +85
°
C). It has output short-circuit protection along
with ESD protection to 8 kV using a human body model. It is
available in 16-ball 1.6 mm × 1.6 mm wafer level chip scale
package (WLCSP).
