... OPERATION The LTC2634 is a family of quad voltage output DACs in 16-lead QFN and 10-lead MSOP packages. Each DAC can operate rail-to-rail using an external reference, or with its full-scale voltage set by an integrated reference. Eighteen combinations of accuracy (12-, 10- and 8-bit), power-on reset value (zero-scale, mid-scale in internal reference mode, or mid-scale in external reference mode), and full- scale voltage (2 ...

... The reference mode of LTC2634-HZ/LTC2634-LZ/ LTC2634-HMI/LTC2634-LMI (internal reference power-on default), can be changed by software command after power up. The same is true for LTC2634-HMX/-LMX (external reference power-on default). The LTC2634’s QFN package offers a REFLO pin for the negative reference. REFLO must be connected to GND.

... LDAC pin) that powers up the DACs will also power up the integrated reference. Voltage Output The LTC2634’s integrated rail-to-rail amplifi er has guaran- teed load regulation when sourcing or sinking up to 10mA at 5V, and 5mA at 3V. Load regulation is a measure of the amplifi er’s ability to maintain the rated voltage accuracy over a wide range of load current ...
