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 users to select the amount of resolution appropriate for their applications without circuit card changes.
The AD7392/AD7393 are specified for operation over the extended industrial (–40° C to +85°C) temperature range.
The AD7393AR is specified for the –40°C to +125°C automotive temperature range.
AD7392/AD7393s are available in plastic DIP, and 20-lead SOIC packages.
The AD7393ARU is available for ultracompact applications in a thin 1.
1 mm height TSSOP-20 package.
For serial data input, 8-lead pac...
