Description
General part information
AD7304 Series
The AD7304 /AD7305are 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, +5.5 V to ±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 VREFinput to DAC VOUTallows for a full-scale voltage set equal the positive supply VDD, the negative supply VSSor any value in between.The AD7304's doubled-buffered serial-data interface offers high-speed, three-wire, SPI and micro controller compatible inputs using data in (SDI), clock (CLK) and chip select (CS) pins.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 aLDACcontrol strobe which copies all the new data into the DAC registers thereby updating the analog output values. The AD7305 is pin-compatible with the popular industry standard AD7226 when operating from less than +5.5 V.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 tri-stating the SDI/SHDN pin on the AD7304, and tri-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.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.APPLICATIONSAutomotive output span voltageInstrumentation, digitally controlled calibrationPin-compatible AD7226 replacement when VDD < 5.5 V
