Description
The MT91L62 3 V 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 3 V device employing a fully
differential architecture to ensure wide dynamic range.
An analog output driver is provided, capable of driving
a 20 k ohm load.
The MT91L62 is fabricated in Zarlink's ISO
2
-CMOS
technology ensuring low power consumption and high
reliability.
