Terminal Functions
TERMINAL
DESCRIPTION
NAME
NO.
DESCRIPTION
AGND
3, 7, 20,
46, 47
Analog ground for analog sections
COSC
48
Capacitor I/O for ramp generator. Adjust the capacitor size to change the switching frequency.
CP1
25
First diode node for charge pump
CP2
24
First inverter switching node for charge pump
CP3
23
Second diode node for charge pump
CP4
26
Second inverter switching node for charge pump
FAULT0
42
Logic level fault0 output signal. Lower order bit of the two fault signals with open drain output.
FAULT1
41
Logic level fault1 output signal. Higher order bit of the two fault signals with open drain output.
LCOMP
6
Compensation capacitor terminal for left-channel Class-D amplifier
LINN
4
Class-D left-channel negative input
LINP
5
Class-D left-channel positive input
LOUTN
14, 15
Class-D amplifier left-channel negative output of H-bridge
LOUTP
10, 11
Class-D amplifier left-channel positive output of H-bridge
LPVDD
9, 16
Class-D amplifier left-channel power supply
LSBIAS
28
Level-shifter power supply, to be tied to VCP
MUTE
2
Active-low logic-level mute input signal. When MUTE is held low, the selected amplifier is muted. When MUTE
is held high, the device operates normally. When the Class-D amplifier is muted, the low-side output transistors
are turned on, shorting the load to ground.
NC
17, 18, 19,
30, 31
No internal connection
PGND
12, 13
Power ground for left-channel H–bridge only
PGND
27
Power ground for charge pump only
PGND
36, 37
Power ground for right-channel H-bridge only
PVDD
21, 32
VDD supply for charge-pump and internal logic circuitry
RCOMP
43
Compensation capacitor terminal for right-channel Class-D amplifier
RINN
45
Class-D right-channel negative input
RINP
44
Class-D right-channel positive input
RPVDD
33, 40
Class-D amplifier right-channel power supply
ROUTN
34, 35
Class-D amplifier right-channel negative output of H-bridge
ROUTP
38, 39
Class-D amplifier right-channel positive output of H-bridge
SHUTDOWN
1
Active-low logic-level shutdown input signal. When SHUTDOWN is held low, the device goes into shutdown
mode. When SHUTDOWN is held at logic high, the device operates normally.
V2P5
29
2.5-V internal reference bypass
VCP
22
Storage capacitor terminal for charge pump
VDD
8
VDD bias supply for analog circuitry. This terminal needs to be well filtered to prevent degrading the device
performance.
