AD7305BRUZ-REEL7

AD7305 is a rail-to-rail quad, 8bit DAC. The reference input range includes both supply rails, allowing for positive or negative full-scale output voltages. 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 parallel input AD7305 uses a standard address decode along with the active-low 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 active-low LDAC control strobe that copies all the new data into the DAC registers, thereby updating the analogue output values. Typical applications are automotive output span voltage, instrumentation, digitally controlled calibration, pin-compatible AD7226 replacement when VDD <lt/> 5.5V.

• Rail-to-rail REF input to voltage output swing, internal power-on reset, fast parallel interface
• Rail-to-rail REF input to voltage output swing, internal power-on reset, fast parallel interface
• An internal power-on reset places both parts in the zero-scale state at turn-on
• Integral nonlinearity is ±1LSB max (VDD=3V or 5V, VSS=0V; or VDD=+5V, −40°C <lt/> TA <lt/> +85°C/+125°C)
• Zero-scale error is 15mV max (3V ± 10%, data=0x00, VDD=3V or 5V, VSS=0V; or VDD=+5V and VSS=–5V)
• Full-scale temperature is 5ppm/°C typ (3V ± 10%, data=0x00, VDD=3V or 5V, VSS=0V)
• Output slew rate is 1/2.7V/µs min/typ (code=0x00 to 0xFFto 0x00, 3V ± 10%, −40 <lt/> TA <lt/> +85°C/+125°C)
• 20-lead TSSOP package
• temperature rating range from –40°C to +85°C
