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 RL = 3 kΩ, CL =
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. VFS is tested under load RL but does not include attenuation due to ZOUT
