MSM7507-01GS-K

Single Rail CODEC

Oki Electric Industry 

¡ Semiconductor

MSM7507-01/02/03

SG

Signal ground voltage output.

The output voltage is 1/2 of the power supply voltage.

The output drive current capability is ±300 mA.

This pin provides the SG level for CODEC peripherals.

This output voltage level is undefined during power saving or power down modes.

SGC

Used to generate the signal ground voltage level by connecting a bypass capacitor.

Connect a 0.1 mF capacitor with excellent high frequency characteristics between the AG pin and

the SGC pin.

ALAW

Control signal input of the companding law selection.

Provides only for the MSM7507-01GS-K/7507-01MS-K. The CODEC will operate in the m-law

when this pin is at a logic "0" level and the CODEC will operate in the A-law when this pin is at

a logic "1" level. The CODEC operates in the m-law if the pin is left open, since the pin is internally

pulled down.
