DS3904 - Triple 128-Bit Non-Volatile 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 operate from a 2.7V to 5.5V supply voltage range and communicate with the device through a 2-wire serial interface. The address pin allows multiple DS3904/DS3905s to operate on the same two-wire bus. The DS3904 has an address pin , allowing two DS3904s to share the bus, while the DS3905 has three address pins, allowing up to eight DS3905s to all have a common bus. The low cost and small size of the DS3904/DS3905 make them an ideal replacement for traditional mechanical trimmer resistors .
