DAC8832 PARAMETER CONDITIONS MIN TYP MAX UNIT STATIC PERFORMANCE Resolution 16 bits DAC8832ICRGY ±0.5 ±1 Linearity error DAC8832IBRGY ±0.5 ±2 LSB DAC8832IRGY ±0.5 ±4 Differential linearity error All grades ±0.5 ±1 LSB TA = +25°C ±1 ±5 Gain error LSB TA = –40°C to +85°C ±7 Gain drift ±0.1 ppm/ °C TA = +25°C ±0.25 ±1 Zero code error LSB TA = –40°C to +85°C ±2 Zero code drift ±0.05 ppm/ °C OUTPUT CHARACTERISTICS Unipolar operation 0 +VREF V Voltage output (1) Bipolar operation –VREF +VREF V Output impedance 6.25 k Ω Settling time To 1/2 LSB of FS, CL = 10 pF 1 μs Slew rate(2) CL = 10 pF 25 V/ μs Digital-to-analog glitch 1 LSB change around major carry 35 nV-s Digital feedthrough(3) 0.2 nV-s Output noise TA = +25°C 18 nV/ √Hz Power-supply rejection VDD varies ±10% ±1 LSB RFB / RINV 1 Ω/Ω Bipolar resistor matching Ratio error ±0.0015 ±0.0076 % TA = +25°C ±0.25 ±5 Bipolar zero error LSB TA = –40°C to +85°C ±7 Bipolar zero drift ±0.2 ppm/ °C (1) See the Bipolar Output Operation section for details. (2) Slew rate is measured from 10% to 90% of transition when the output changes from 0 to full-scale. (3) 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.
