GENERAL DESCRIPTION
The SSM2380 is a fully integrated, high efficiency, stereo, Class-D
audio amplifier. It is designed to maximize performance for mobile
phone applications. The application circuit requires a minimum
of external components and operates from a single 2.5 V to 5.5 V
supply. It is capable of delivering 2 W of continuous output power
with <1% THD + N driving a 4 Ω load from a 5.0 V supply.
The SSM2380 features a highly flexible I2C interface with many
useful settings. Using the I2C control interface, the gain of the
SSM2380 can be selected from 1 dB to 24 dB (plus mute) in
47 steps with no external components. Other features accessed
from the I2C interface include independent left/right channel
shutdown, variable ultralow EMI emission control mode, auto-
matic level control (ALC) for high quality speaker protection,
and stereo-to-mono mixing operation.
The SSM2380 features a high efficiency, low noise modulation
scheme that requires no external LC output filters. The modulation
continues to provide high efficiency even at low output power.
The SSM2380 operates with 93% efficiency at 1.4 W into 8 Ω
or with 85% efficiency at 2 W into 4 Ω from a 5.0 V supply and
has an SNR of >100 dB.
Spread-spectrum pulse density modulation is used to provide
lower EMI-radiated emissions compared with other Class-D
architectures. An added benefit of spread-spectrum Σ-Δ modu-
lation is that no synchronization (SYNC) is needed when using
multiple Class-D amplifiers. For applications that require long
speaker cables (>10 cm), the SSM2380 includes a user-selectable
ultralow EMI emissions mode that eliminates the need for EMI
filters at the Class-D outputs.
The SSM2380 has a micropower shutdown mode with a typical
shutdown current of 20 nA. Shutdown is enabled by applying
a logic low to the SD pin or through an optional independent
channel soft shutdown via I2C.
The device also includes pop-and-click suppression circuitry.
This suppression circuitry minimizes voltage glitches at the
output during turn-on and turn-off, reducing audible noise
on activation and deactivation.
The fully differential inputs of the SSM2380 provide excellent
rejection of common-mode noise on the input. Input coupling
capacitors can be omitted if the dc input common-mode voltage
is approximately VDD/2.
The SSM2380 is specified over the commercial temperature
range of 40°C to +85°C. It has built-in thermal shutdown
and output short-circuit protection. It is available in a 16-ball,
2 mm × 2 mm wafer level chip scale package (WLCSP).
