2.5 V to 5.5 V, Parallel Interface  
Octal Voltage Output 8-/10-/12-Bit DACs  
AD5346/AD5347/AD5348  
GENERAL DESCRIPTION  
FEATURES  
The AD5346/AD5347/AD53481 are octal 8-, 10-, and 12-bit  
DACs, operating from a 2.5 V to 5.5 V supply. These devices  
incorporate an on-chip output buffer that can drive the output  
to both supply rails, and also allow a choice of buffered or  
unbuffered reference input.  
AD5346: octal 8-bit DAC  
AD5347: octal 10-bit DAC  
AD5348: octal 12-bit DAC  
Low power operation: 1.4 mA (max) @ 3.6 V  
Power-down to 120 nA @ 3 V, 400 nA @ 5 V  
Guaranteed monotonic by design over all codes  
Rail-to-rail output range: 0 V to VREF or 0 V to 2 × VREF  
Power-on reset to 0 V

These devices also incorporate a power-on reset circuit that  
ensures that the DAC output powers on to 0 V and remains  
there until valid data is written to the device.
