DAC ANALOG CHARACTERISTICS
Test conditions (unless otherwise specified): TA = 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.
1_2VRMS = 0

Notes: 2. Measured at the output of the external LPF on AOUTx as shown in Figure 3 on page 12.
3. One-half 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. VPP is the controlling specification. VRMS specification valid for sine wave signals only.
Note that for sine wave signals: VRMS = -V----p---p-
22
8. Measured with AOUT_REF connected directly to ground. External impedance between AOUT_REF
and ground will lower the AOUT_REF rejection.
