3 / 19 page www.ti.com ELECTRICAL CHARACTERISTICS DAC8871 SBAS396 – JUNE 2007 All specifications at T A = TMIN to TMAX, VCC = +15V, VSS = –15V, VREFH = +10V, VREFL = –10V, and VDD = +5V, unless otherwise noted; specifications subject to change without notice. DAC8871 PARAMETER CONDITIONS MIN TYP MAX UNIT STATIC PERFORMANCE Resolution 16 Bits VREFH = 10V, VREFL = –5V ±0.75 ±1 LSB DAC8871B Linearity error VREFH = 10V, VREFL = –10V ±1 ±1.5 LSB DAC8871 ±1 ±3 LSB Differential linearity error ±0.25 ±1 LSB Gain error TA = +25°C ±0.5 ±2 LSB Gain drift ±0.1 ppm/ °C Bipolar zero error TA = +25°C ±1 ±4 LSB Bipolar drift ±0.1 ppm/ °C Zero code error TA = +25°C ±0.5 ±2 LSB Zero code drift ±0.05 ppm/ °C OUTPUT CHARACTERISTICS Voltage output VREFL VREFH V Output impedance 6.25 k Ω Settling time To 1LSB of FS, CL = 15 pF 1 µs Slew rate(1) CL = 15pF 40 V/ µs Digital feedthrough(2) 0.2 nV-s Output noise TA = +25°C 10 nV/ √Hz Power supply rejection Supplies vary ±10% ±1 LSB REFERENCE INPUT VREFH Ref high input voltage range 0 +18 V VREFL Ref low input voltage range –18 VREFH – 1.25 V Ref high input current 1.3 mA Ref low input current –1.3 mA Reference input impedance(3) 7.5 k Ω Code = 0000h 75 pF Reference input capacitance Code = FFFFh 120 pF DIGITAL INPUTS VDD = +5V DGND 0.8 V VIL Input low voltage VDD = +3V DGND 0.6 V VDD = +5V 2.6 VDD V VIH Input high voltage VDD = +3V 2.1 VDD V Input current ±1 µA Input capacitance 10 pF (1) Slew Rate is measure from 10% to 90% of transition when the output changes from 0 to full scale. (2) Digital feedthrough is defined as the impulse injected into the analog output from the digital input. It is measured when the DAC output does not change; CS is held high, while SCLK and DIN signals are toggled. It is specified with a full-scale code change on the SDI bus (that is, from all 0s to all 1s and vise versa). (3) Reference input resistance is code-dependent, with a minimum at 8555h 3 Submit Documentation Feedback |
