DS3904 Datasheet (Dallas Semiconducotr) - Triple 128-Position Nonvolatile Digital Variable Resistor/Switch

DS3904, Triple 128-Position Nonvolatile Digital Variable Resistor/Switch

The DS3904/DS3905 contain three nonvolatile (NV) low temperature coefficient, variable digital resistors.

Each resistor has 128 user-selectable positions.

Additionally, the DS3904/DS3905 have a high-impedance setting that allows each resistor to function as a digital switch.

The DS3904/DS3905 can op
