I/O
I/O for current setting resistor of ramp generator
ROUTN
39, 40
O
Class-D 1/2-H-bridge negative output for right channel
ROUTP
41, 42
O
Class-D 1/2-H-bridge positive output for right channel
Shutdown signal for IC (LOW = disabled, HIGH = operational). TTL logic levels with
SHUTDOWN
44
I
compliance to AVCC.
Clock input/output for synchronizing multiple class-D devices. Direction determined by
SYNC
11
I/O
MSTR/SLV terminal. Input signal not to exceed VREG.
Reference for preamplifier. Nominally equal to 1.25 V. Also controls start-up time via external
VBYP
16
O
capacitor sizing.
VCLAMPL
30
Internally generated voltage supply for left channel bootstrap capacitor
VCLAMPR
31
Internally generated voltage supply for right channel bootstrap capacitor
4-V regulated output for use by internal cells, GAINx, MUTE, and MSTR/SLV pins only. Not
VREG
15
O
specified for driving other external circuitry.
Connect to AGND and PGND. Should be star point for both grounds. Internal resistive
connection to AGND and PGND. Thermal vias on the PCB should connect this pad to a
Thermal Pad
large copper area on an internal or bottom layer for the best thermal performance. The
Thermal Pad must be soldered to the PCB for mechanical reliability.
