VREF VDD GENERAL DESCRIPTION
The AD7304/AD73051 are quad, 8-bit DACs that operate from
a single +3 V to +5 V supply, or В±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 …
