Description
The MT91L62 3V 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
MT91L62 is a true 3V device employing a fully
differential architecture to ensure wide dynamic
range.
An analog output driver is provided, capable of
driving a 20k ohm load.
The MT91L62 is fabricated in Mitel's ISO2-CMOS
technology ensuring low power consumption and
high reliability.
