... The DAC can be put in low current power-down mode for use in power conscious systems. Power-on reset ensures the DAC output when power is initially applied, and all internal registers are cleared. The LTC1669 is pin-for-pin compatible with the LTC1663. , LTC and LT are registered trademarks of Linear Technology Corporation trademark of Philips Electronics N ...

... Don’t care Send Byte Protocol The Send Byte protocol used on the LTC1669 is actually a subset of the Write Word protocol described previously. The Send Byte protocol can only be used to send the command byte information to the LTC1669 Start Condition Write Bit Acknowledge Stop Condition The Send Byte protocol is also used whenever the Write Word protocol is interrupted for any reason ...

... For example, a 0.1 F load can be driven by the LTC1669 if a 110 series resistance is used. The phase margin of the resulting circuit is 45 and increases mono- tonically from this point if larger values of resistance, ca- pacitance or both are substituted for the values given ...
