The AD7304/AD73051 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 full-scale 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.
