14/85

1EARNS

EARPS, EARNS (sense) pins must be connected on the application

board to EARP, EARN pins respectively. The connection must be as

close as possible to the pins.

VCCLS

Power supply pins for the mono differential output driver. Operating

range: from VCCA to 5.5V

K10

1ORP

Audio differential line out amplifier for left and right channels. This

outputs can drive up to 1k

Ω resistive load. Can be used as single

ended output.

K11

GNDP

Ground pin for the left, right and mono-differential output drivers.

GNDP and GNDA must be connected together.

VCCP

Power supply pin for the left and right output drivers (headphones

and line-out).

Operating range: from VCCA to 3.3V

GNDP

Ground pin for the left, right and mono-differential output drivers.

GNDP and GNDA must be connected together.

1VCMHPS

VCMHPS (sense) pin must be connected on the application board to

VCMHP pin. The connection must be as close as possible to the

pins.

2VCMHP

Common mode voltage headphones output. The negative pins of

headphones left and right speakers can be connected to this pin to

avoid decoupling capacitors.

2LSPS

LSPS, LSNS (sense) pins must be connected on the application

board to LSP, LSN pins respectively. The connection must be as

close as possible to the pins.

2LSP

Analog differential loudspeaker amplifier output for Left channel or

Right channel or the sum of both. This output can drive 50nF (with

series resistor) or directly an earpiece transductor of 8

Ω.; It can

deliver up to 500mW.

2CAPLS

A capacitor can be connected between this node and ground

2LSN

Analog differential loudspeaker amplifier output for Left channel or

Right channel or the sum of both. This output can drive 50nF (with

series resistor) or directly an earpiece transductor of 8

Ω. Can deliver

up to 500mW.

2LSNS

LSPS, LSNS (sense) pins must be connected on the application

board to LSP, LSN pins respectively. The connection must be as

close as possible to the pins.

L10

VCCP

Power supply pin for the left and right output drivers (headphones

and line-out). Operating range: from VCCA to 3.3V

L11

2HPR

Audio single ended headphones amplifier outputs for left and right

channels. The outputs can drive 50nF (with series resistor) or

directly an earpiece transductor of 16

Ω.
