2.1 DS160PR412 and DS160PR421 4-Level I/O Control Inputs

Each DS160PR412 and DS160PR421 features 4-level input pins (MODE, GAIN/SDA, EQ0/ADDR, EQ1, and RX_DET/SCL) that are used to control the configuration of the device. These 4-level inputs use a resistor divider to help set the four valid levels to provide a wider range of control settings.
