... Once a plug is inserted, this connection is broken. Referring to Figure 12, Pin 4 of the SSM2250 is connected to the normalizing pin for the right channel output. This is the pin in the headphone jack that will hit the ring on the headphone plug. ...

... will create a corner frequency of 8 Hz. This is acceptable, as the PC 99 audio requirement specifies the com- puter audio system bandwidth kHz. Pin 10 on the SSM2250 provides the proper bias voltage for the amplifiers. A 0.1 F capacitor should be connected here to reduce sensitivity to noise on the power supply. A larger capaci- tor can be used should more rejection from power supply noise be required ...

... It can be easily seen that power into a speaker can produce quite a bit of acoustic energy Shutdown Feature L The SSM2250 can be put into a low power consumption shut- down mode by connecting Pin SSM2250 has low supply current Pin 3 should be connected to ground for normal operation. Con- necting Pin ...

... The AD1881 is an AC’97 Ver. 2.1 audio codec available from Analog Devices. The stereo output from the AD1881 is coupled into the SSM2250, which is used to drive a mono internal speaker and stereo headphones. The internal speaker switching is controlled by the SSM2250 through the normalizing pin on the headphone jack ...
