DAC ANALOG CHARACTERISTICS
Test conditions (unless otherwise specified): T
A
= 25 °C; VA = 5 V, VL = 3.3 V; GND = 0 V; FILT+, -VFILT, and
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.
6. Does not include attenuation due to Z
OUT
. Additional impedance between the AOUTx pin and the load
will lower the voltage delivered to the load.
7. V
PP
is the controlling specification. V

specification valid for sine wave signals only.
Note that for sine wave signals:
