• description

  LTC^®The 2637 is an 8-channel family of 12-, 10-, and 8-bit voltage output DACs featuring an integrated, high accuracy, low drift 10ppm/°C reference in 14-pin DFN and 16-pin MSOP packages. It has a built-in rail-to-rail output buffer and is guaranteed monotonic. The LTC2637-L has a 2.5V full-scale output and operates from a single 2.7V to 5.5V supply. The LTC2637-H has a 4.096V full-scale output and operates from a single 4.5V to 5.5V supply. Each DAC can also operate with an external reference that sets the DAC full-scale output as an external reference voltage.

  These DACs go through a two-wire I²C-compatible serial interface for communication. The LTC2637 operates in standard mode (100kHz clock frequency) and fast mode (400kHz clock frequency). The LTC2637 contains a power-on reset circuit. Options are provided to reset to zero scale in internal reference mode or reset to intermediate scale after power-up, or reset to midscale in external reference mode.
