I/O DESCRIPTION
NAME NO.
BYPASS 16 I Tap to voltage divider for internal midsupply bias generator used for analog reference
Places the amplifier in fade mode if a logic low is placed on this terminal; normal operation if a logic high is
FADE 15 I
placed on this terminal.
AGND 17 - Analog power supply ground
LIN- 7 I Left channel negative input for fully differential input.
LIN+ 8 I Left channel positive input for fully differential input.
LOUT– 10 O Left channel negative audio output
LOUT+ 12 O Left channel positive audio output.
NC 13 - No connection
PGND 1, 11 - Power ground
PVDD 3, 9 - Supply voltage terminal for power stage
RIN- 5 I Right channel negative input for fully differential input.
RIN+ 4 I Right channel positive input for fully differential input.
ROUT– 2 O Right channel negative audio output
ROUT+ 20 O Right channel positive audio output
Output control. When this terminal is high, SE outputs are selected. When this terminal is low, BTL outputs
SE/ BTL 19 I
are selected.
SHUTDOWN 14 I Places the amplifier in shutdown mode if a TTL logic low is placed on this terminal
VDD 6 - Supply voltage terminal
VOLUME 18 I Terminal for dc volume control. DC voltage range is 0 to V
