The AD7304/AD7305 are quad, 8-bit DACs that operate from a single +3 V to +5 V supply or 5 V supplies. The AD7304 has a serial interface, while the AD7305 has a parallel interface. Internal precision buffers swing rail-to-rail. The reference input range includes both supply rails allowing for positive or negative fullscale output voltages. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V, consuming less than 9 mW from a +3 V supply.
