description

LTC^®The 2631 is a family of 12-, 10-, and 8-bit voltage-output DACs in an 8-pin TSOT-23 package with an integrated, high-accuracy, low-drift reference. It has a built-in rail-to-rail output buffer and is guaranteed monotonic.

The LTC2631-L has a 2.5V full-scale output and operates from a single 2.7V to 5.5V supply. The LTC2631-H has a full-scale output of 4.096V and operates from a single 4.5V to 5.5V supply. A 10ppm/°C reference output is provided on the REF pin.

Each DAC operates in an external reference mode, where a voltage supplied to the REF pin sets the full-scale output.

The LTC2631 DAC uses a 2-wire, I²C-compatible serial interface. The LTC2631 operates in both standard mode (100kHz clock frequency) and fast mode (400kHz clock frequency).

The LTC2631 contains a power-on reset circuit. Options are available to reset to zero scale or reset to intermediate scale after power-up.
