SG

Signal ground voltage output.

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

The output drive current capability is ±300 mA for ML7000-xx and ±200 mA for ML7001-xx.

This pin provides the SG level for CODEC peripherals.

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

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.

Only the ML7000-01MA/ML7000-01MB/ML7001-01MA/ML7001-01MB have this pin. 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.
