DAC ANALOG CHARACTERISTICS - COMMERCIAL (-CQZ)
Test Conditions (unless otherwise specified): VA = VD = VL = 3.3 V, VA_H = 9 V, GND = GNDH = 0 V; TA = 25° C;
997 Hz Full-Scale Output Sine Wave. Decoupling capacitors, Filter capacitors, and Recommended output filter as
shown in Figure 7 on page 26 and Figure 8 on page 27; Fs = 48 kHz or 96 kHz; Synchronous Mode; Measurement
Bandwidth 10 Hz to 20 kHz,
Notes: 7.
One-half LSB of triangular PDF dither added to data.
8.
Does not account for attenuation due to ZOUT.
9.
See Figures 1 and 2 on page 19. RL and CL reflect the minimum resistance and maximum capacitance
allowed in order to maintain stability in the internal op-amp. CL affects the dominant pole of the internal
output amp; increasing CL beyond 100 pF can cause the internal op-amp to become unstable.
