DAC ANALOG CHARACTERISTICS - COMMERCIAL GRADE

(Notes 3 to 7)

Notes: 3. One-half LSB of Triangular PDF dither is added to data.

4. Performance measurements taken with a full-scale 997 Hz sine wave under Test load R

L

= 3 k

Ω, C

L

=

10 pF

5. Measurement bandwidth is 10 Hz to 20 kHz.

6. Logic “0” = GND = 0V; Logic “1” = VL; VL = VA unless otherwise noted.

7. V

FS

is tested under load R

L

but does not include attenuation due to Z
