LTC2637CMS-LMI10-PBF Dual 12-/10-/8-Bit I2C VOUT DACs with10ppm/°C Reference MSOP16 spot stock

Product Descriptions

The LTC®2633 is a family of dual 12-, 10-, and 8-bit  voltage-output DACs with an integrated, high accuracy,  low drift reference in an 8-lead TSOT-23 package. It has  rail-to-rail output buffers and is guaranteed monotonic.  The LTC2633-L has a full-scale output of 2.5V, and operates  from a single 2.7V to 5.5V supply. The LTC2633-H has a  full-scale output of 4.096V, and operates from a 4.5V to  5.5V supply. Each DAC can also operate with an external  reference, which sets the full-scale output to the external  reference voltage.

These DACs communicate via a 2-wire I2C-compatible  serial interface. The LTC2633 operates in both the standard  mode (clock rate of 100kHz) and the fast mode (clock rate  of 400kHz). The LTC2633 incorporates a power-on reset  circuit. Options are available for reset to zero-scale, reset  to mid-scale in internal reference mode, reset to mid-scale  in external reference mode, or reset with all DAC outputs  in a high impedance state after power-up.
