Description
The MT9162 5V single rail Codec incorporates a
built-in Filter/Codec, transmit anti-alias filter, a
reference voltage and bias source. The device
supports both A-law and
µ-law
requirements.
The analog interface is capable of driving a 20k ohm
load.
The MT9162 is fabricated in Mitel's ISO
2
-CMOS
technology ensuring low power consumption and
high reliability.
