... The LTC2605/LTC2615/LTC2625 clear the outputs to zero scale when power is first applied, making system initialization consistent and repeatable. The LTC2605-1/ LTC2615-1/LTC2625-1 set the voltage outputs to midscale when power is first applied. For some applications, downstream circuits are active during DAC power-up, and may be sensitive to nonzero outputs from the DAC during this time ...

... CA0, CA1 and CA2 and the global address are shown in Table 2. In addition to the address selected by the address pins, the parts also respond to a global address. This address allows a common write to all LTC2605, LTC2615 and LTC2625 parts to be accomplished with one 3-byte write transaction 2 on the I C bus ...

... LTC2605/LTC2615/LTC2625 U OPERATIO The command (C3-C0) and address (A3-A0) assignments are shown in Table 1. The first four commands in the table consist of write and update operations. A write operation loads the 16-bit data word from the 32-bit shift register into the input register of the selected DAC update operation copies the data word from the input register to the DAC register ...

... Resistance here will add directly to the effective DC output impedance of the device (typically 0.020Ω), and will degrade DC crosstalk. Note that the LTC2605/LTC2615/LTC2625 are no more susceptible to these effects than other parts of their type; on the contrary, they allow layout-based performance improvements to shine rather than limiting attainable performance with excessive internal resistance ...
