TERMINAL FUNCTIONS
TERMINAL
I/O DESCRIPTION
NO. NAME
AGND 12 - Analog ground
BYPASS 22 I Tap to voltage divider for internal mid-supply bias generator used for internal analog reference.
COSC 10 I A capacitor connected to this terminal sets the oscillation frequency in conjunction with ROSC. For
proper operation, connect a 220-pF capacitor from COSC to ground.
LINN 1 I Negative differential audio input for left channel
LINP 2 I Positive differential audio input for left channel
LOUTN 8 O Negative audio output for left channel
LOUTP 5 O Positive audio output for left channel
NC 15 I No connection
PGNDL 6, 7 - Power ground for left channel H-bridge
PGNDR 18, 19 - Power ground for right channel H-bridge
PVDDL 4, 9 Power supply for left channel H-bridge
PVDDR 16, 21 Power supply for right channel H-bridge
RINN 24 I Positive differential audio input for right channel
RINP 23 I Negative differential audio input for right channel
ROSC 11 I A resistor connected to the ROSC terminal sets the oscillation frequency in conjunction with COSC. For
proper operation, connect a 120-kΩ resistor from ROSC to ground.
ROUTN 17 O Negative output for right channel
ROUTP 20 O Positive output for right channel
SHUTDOWN 3 I Places the amplifer in shutdown mode if a TTL logic low is placed on this terminal; normal operation if a
TTL logic high is placed on this terminal.
VDD 13 - Analog power supply
VOLUME 14 I DC volume control for setting the gain on the internal amplifiers. The dc voltage range is 0 to VDD.
Thermal Pad - - Connect to analog ground and the power grounds must be soldered down in all applications to properly
secure device on the PCB.
