DAC ANALOG CHARACTERISTICS
Test conditions (unless otherwise specified): T
A
= 25 °C; VCP = VA = 3.3 V; AOUT_REF = AGND = DGND =
CPGND = 0 V; VBIAS, VFILT+/-, and FLYP/N+/- capacitors as shown in Figure 3 on page 12; input test signal is a
997 Hz sine wave at 0 dBFS; measurement bandwidth 10 Hz to 20 kHz.
Notes: 2. Measured at the output of the external LPF on AOUTx as shown in Figure 3 on page 12.
3. One LSB of triangular PDF dither is added to data.
4. Measured with the specified minimum AC-Load Resistance present on the AOUTx pins.
5. Measured between the AOUTx and AOUT_REF pins.
6. External impedance between the AOUTx pin and the load will lower the voltage delivered to the load.
7. V
PP
is the controlling specification. V
RMS
specification valid for sine wave signals only.
Note that for sine wave signals:
8. Measured with AOUT_REF connected directly to ground. External impedance between AOUT_REF
and ground will lower the AOUT_REF rejection.
