3 / 17 page Parameter A Grade 2 Units Test Conditions/Comments ACCURACY Resolution 12 Bits 1 LSB = (VIOUT2 – VREF)/2 12 = 300 µV when VIOUT2 = 1.23 V and VREF = 0 V Relative Accuracy ±1 LSB max Differential Nonlinearity ±0.9 LSB max All Grades Guaranteed Monotonic Over Temperature Gain Error +25 °C ±4 LSBs max TMIN to TMAX ±5 LSBs max Gain Temperature Coefficient 3 2 ppm FSR/ °C typ 5 ppm FSR/ °C max Output Leakage Current See Terminology Section IOUT1 @ +25 °C 10 nA max TMIN to TMAX 50 nA max Input Resistance @ IOUT2 Pins 6 k Ω min This Varies with DAC Input Code DIGITAL INPUTS VINH, Input High Voltage @ VDD = +5 V 2.4 V min VINH, Input High Voltage @ VDD = +3.3 V 2.1 V min VINL, Input Low Voltage @ VDD = +5 V 0.8 V max VINL, Input Low Voltage @ VDD = +3.3 V 0.6 V max IINH, Input Current ±1 µA max CIN, Input Capacitance 3 10 pF max DIGITAL OUTPUT (SDOUT) Load Circuit as in Figure 2. Output Low Voltage (VOL) 0.4 V max VDD = +5 V Output Low Voltage (VOL) 0.2 V max VDD = +3.3 V Output High Voltage (VOH) 4.0 V min VDD = +5 V Output High Voltage (VOH)VDD – 0.2 V min VDD = +3.3 V POWER REQUIREMENTS VDD Range 3/5.5 V min/V max Power Supply Sensitivity 3 ∆Gain/∆V DD –75 dB typ IDD 10 µA max VINH = VDD – 0.1 V min, VINL = 0.1 V max; SDOUT Open Circuit IDD is typically 2 mA with VDD = +5 V, VINH = 2.4 V min, VINL = 0.8 V max; SDOUT Open Circuit NOTES 1These specifications apply with the devices biased up at 1.23 V for single supply applications. The model numbering reflects this by means of a "-B" suffix (for example: AD7564AR-B). Figure 19 is an example of Biased Mode Operation. 2Temperature ranges is as follows: A Version: –40 °C to +85°C. 3Not production tested. Guaranteed by characterization at initial product release. Specifications subject to change without notice. Biased Mode1 (VDD = +3 V to +5.5 V; VIOUT1 = VIOUT2 = 1.23 V; AGND = 0 V; VREF = 0 V to 2.45 V; TA = TMIN to TMAX, unless otherwise noted) –3– REV.
