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: 3.

One-half LSB of triangular PDF dither added to data.

See Figures 1 and 2 on page 16. 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.
