GENERAL DESCRIPTION
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.
The full-scale voltage output is determined by the external
reference input voltage applied. The rail-to-rail VREF input to
DAC VOUT allows for a full-scale voltage set equal to the positive
supply, VDD, the negative supply, VSS, or any value in between.
The AD7304’s doubled-buffered serial data interface offers high
speed, 3-wire, SPI®-, and microcontroller-compatible inputs
using data in (SDI), clock (CLK), and chip select (CS) pins.
Additionally, an internal power-on reset sets the output to zero
scale.
The parallel input AD7305 uses a standard address decode
along with the WR control line to load data into the input
registers.
The double-buffered architecture allows all four input registers
to be preloaded with new values, followed by an LDAC control
strobe that copies all the new data into the DAC registers,
thereby updating the analog output values.

Figure 2.
When operating from less than 5.5 V, the AD7305 is
pin-compatible with the popular industry-standard AD7226.
An internal power-on reset places both parts in the zero-scale
state at turn-on. A 40 µA power shutdown (SHDN) feature is
activated on both parts by three-stating the SDI/SHDN pin on
the AD7304 and three-stating the A0/SHDN address pin on the
AD7305.
The AD7304/AD7305 are specified over the extended industrial
−40°C to +85°C and the automotive −40°C to +125°C
temperature ranges. AD7304s are available in a wide-body
16-lead SOIC (R-16) package. The parallel input AD7305 is
available in the wide-body 20-lead SOIC (R-20) surface-mount
package. For ultracompact applications, the thin 1.1 mm,
16-lead TSSOP (RU-16) package is available for the AD7304,
while the 20-lead TSSOP (RU-20) houses the AD7305.
