NOTES ON USAGE

Type of the Built-in D/A Converter

ML2201 has the built-in current-output type D/A converter and thus the design of analog output circuit is different

from the one with a voltage-output type D/A converter (e.g. MSM6650 family).

ML2201’s D/A converter is designed as current attraction type with the same circuit configuration with the one

used on MSM9831. So, the analog output circuit is different from MSM9800 family that uses a current discharge

type D/A converter. (See the table below)
