Built using a CBCMOS process, these monolithic DACs offer the user low cost and ease of use in single-supply +3 V systems. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V, making this device ideal for battery operated applications. The full-scale voltage output is determined by the external reference input voltage applied. The rail-to-rail REFIN to DACOUT allows for a full-scale voltage set equal to the positive supply VDD or any value in between. The voltage outputs are capable of sourcing 5 mA. A 12-bit wide data latch loads with a 45 ns write time allowing interface to the fastest processors without wait states. 1 Additionally, an asynchronous RS input sets the output to zero scale at power on or upon user demand. Both parts are offered in the same pinout to allow us...
