DAC ANALOG CHARACTERISTICS

FLYP/N capacitors as shown in Figure 5 on page 12; input test signal is a 997 Hz sine wave at 0 dBFS; measure-

ment bandwidth 20 Hz to 20 kHz.

Notes: 3. Measured at the output of the external low-pass filter on AOUTx as shown in Figure 5 on page 12.

4. Measured between the AOUTx and GND pins.

5. One LSB of triangular PDF dither is added to data.

will lower the voltage delivered to the load.
