Pinout

13/85

1OLP

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.

2OLP

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.

2HPL

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.

1VCMHP

Common mode voltage headphones output. The negative pins of

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

avoid decoupling capacitors.

1CAPEAR

A capacitor can be connected between this node and ground

1EARN

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 from 8

Ω to 32Ω.;

It can deliver from 500mW to 125mW.

VCCLS

Power supply pin for the mono differential output driver. Operating

range: from VCCA to 5.5V

2ORP

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.

J10

1ORN

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.

J11

1LINEINR

Left and right channel single ended pins for line input

GNDCM

Ground pin for analog reference.

GNDCM can be connected to GNDA

VCCP

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

and line-out).

Operating range: from VCCA to 3.3V

1HPL

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.

2VCMHPS

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

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

pins.

VCCLS

Power supply pin for the mono differential output driver. Operating

range: from VCCA to 5.5V

GNDP

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

GNDP and GNDA must be connected together.

GNDP

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

GNDP and GNDA must be connected together.
