SBAS438A – MAY 2008 – REVISED AUGUST 2008 All specifications at TA = TMIN to TMAX, AVDD = +4.75V to +5.5V, IOVDD = +1.8V to +5.5V, VREFH = 5V, VREFL = 0V, and gain = 1X mode, unless otherwise noted. DAC9881 PARAMETER CONDITIONS MIN TYP MAX UNIT ACCURACY(1) Measured by line DAC9881S ±2 ±3 LSB passing through Integral linearity error codes 2048 and DAC9881SB ±1 ±2 LSB 260096 Measured by line DAC9881S –1 ±0.75 +2 LSB passing through Differential linearity error codes 2048 and DAC9881SB ±0.5 ±1 LSB 260096 Monotonicity 18 Bits TA = +25°C, code = 2048 ±16 LSB Zero-scale error TMIN to TMAX, code = 2048 ±32 LSB Zero-scale drift(2) Code = 2048 ±0.25 ±0.8 ppm/°C of FSR TA = +25°C, measured by line passing through codes 2048 Gain error ±16 ±32 LSB and 260096 Gain temperature drift(2) Measured by line passing through codes 2048 and 260096 ±0.25 ±0.4 ppm/°C PSRR(2) VOUT = full-scale, AVDD = +5V ±10% 32 LSB/V ANALOG OUTPUT(2) Voltage output(3) 0 AVDD V Device operating for 500 hours at +25°C 0.1 ppm of FSR Output voltage drift vs time Device operating for 1000 hours at +25°C 0.2 ppm of FSR Output current(4) 2.5 mA Maximum load capacitance 200 pF Short-circuit current +31/–50 mA REFERENCE INPUT(2) VREFH input voltage range AVDD = +5.5V 1.25 5.0 AVDD V VREFH input capacitance 5 pF VREFH input impedance 4.5 k Ω VREFL input voltage range –0.2 0 +0.2 V VREFL input capacitance 4.5 pF VREFL input impedance 5 k Ω DYNAMIC PERFORMANCE(2) To ±0.003% FS, RL = 10kΩ, CL = 50pF, code 04000h to Settling time 5 µs 3C000h Slew rate From 10% to 90% of 0V to +5V 2.5 V/ µs VREFH = 5V, gain = 1X mode 37 nV-s VREFH = 2.5V, gain = 1X mode 18 nV-s Code = 1FFFFh to Code change glitch VREFH = 1.25V, gain = 1X mode 9 nV-s 20000h to 1FFFFh VREFH = 2.5V, gain = 2X mode 21 nV-s VREFH = 1.25V, gain = 2X mode 10 nV-s Digital feedthrough CS = high, fSCLK = 1kHz 1 nV-s Gain = 1 24 30 nV/ √Hz f = 1kHz to 100kHz, Output noise voltage density full-scale output Gain = 2 40 48 nV/ √Hz Output noise voltage f = 0.1Hz to 10Hz, full-scale output 2 µV PP (1) DAC output range is 0V to +5V. 1LSB = 19 µV. (2) Ensured by design. Not production tested. (3) The output from the VOUT pin = [(VREFH – VREFL)/262144] × CODE × Buffer GAIN + VREFL. The maximum range of VOUT is 0V to AVDD. The full-scale of the output must be less than AVDD; otherwise, output saturation occurs. (4) Refer to Figure 26, Figure 27, and Figure 28 for details.
