RT9406
2-CH I2C-Controlled Reference Generator
General Description
The RT9406 is a universal DAC generator which supports
VID on-the-fly function with five different slew rates : Fast,
Fast/2, Fast/4, Fast/8 and Fast/16. An I2C interface is built
in the RT9406 to communicate with microprocessors. The
reference voltage is within 1% accuracy. The RT9406 also
provides pins to determine the initial voltage of Vref1 and
Vref2. The RT9406 is available in the SOT-23-8 package.
Features

Note 1. Stresses beyond those listed “Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in
the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions may
affect device reliability.
Note 2. θJA is measured at TA = 25°C on a high effective thermal conductivity four-layer test board per JEDEC 51-7.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
