DAC ANALOG CHARACTERISTICS
Test conditions (unless otherwise specified): TA = 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.
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 ZOUT. Additional impedance between the AOUTx pin and the load
will lower the voltage delivered to the load.
7.
VPP is the controlling specification. VRMS specification valid for sine wave signals only.
Note that for sine wave signals:
