7. CHARACTERISTICS/SPECIFICATIONS

ANALOG CHARACTERISTICS (CS4392-KS/KZ) ((Test conditions (unless otherwise speci-

fied): Input test signal is a 997 Hz sine wave at 0 dBFS; measurement bandwidth is 10 Hz to 20 kHz; test load

RL =3kΩ,CL = 10 pF. Typical performance characteristics are derived from measurements taken at TA =25 °C,

VL = VA = 5.0V. Min/Max performance characteristics are guaranteed over the specified operating temperature

and voltages.)

Notes: 1. One-half LSB of Triangular PDF dither is added to data.

2. VFS is tested under load RL but does not include attenuation due to ZOUT
