2.6.4 Speaker Signals

Pin	Speaker signals	Dir	Function

55	BEARP	O	Speaker positive output

56	BEARN	O	Speaker negative output

BEARP and BEARN are the speaker output pins. These are differential-mode outputs. The electrical characteristics are given in the table below.

Parameter	Limit

Output level (differential)	≥4.0Vpp
Output level (dynamic load = 32Ω)	≥2.8Vpp

Gain PCMINa to BEARP/BEARN (differential)	–9dB ± 1
Distortion at 1kHz and maximum output level	≤5%

Offset, BEARP to BEARN	±30mV

Ear-piece mute-switch attenuation	≥40dB

a. See PCMIN signal in “2.7 PCM Digital Audio”, page 52

The following table shows the ear piece impedances that can be connected to BEARP and BEARN.

Ear piece model	Impedance	Tolerance

Dynamic ear piece	[32Ω + 800µH] // 100pF	±20%

Dynamic ear piece	[150Ω + 800µH] // 100pF	±20%

Piezo ear piece	1kΩ + 60nF	±20%
