General Description
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 over a 2.7V to 5.5V supply
voltage range, and communication with the device is
achieved through a 2-wire serial interface. Address pins
allow multiple DS3904/DS3905s to operate on the same
two-wire bus. The DS3904 has one address pin, allow-
ing two DS3904s to share the bus, while the DS3905
has three address pins, allowing up to eight DS3905s to
share a common bus. The low-cost and small size of the
DS3904/DS3905 make them ideal replacements for con-
ventional mechanical trimming resistors.
