DAC ANALOG CHARACTERISTICS (COMMERCIAL - CNZ)
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 13; input test signal is a
997 Hz sine wave at 0 dBFS; measurement bandwidth 10 Hz to 20 kHz.

Notes: 2. Measured between the AOUTx and AOUT_REF pins.
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. Additional im-
pedance between the AOUTx pin and the load will lower the voltage delivered to the load.
5. V_PP is the controlling specification. V_RMS specification valid for sine wave signals only.
Note that for sine wave signals: VRMS = -^V----^p---^p-
22
6. Measured with AOUT_REF connected directly to ground. Additional impedance between AOUT_REF
and ground will lower the AOUT_REF rejection.
7. SDIN = 0. AOUT_REF input test signal is a 60 Hz, 50 mVpp sine wave. Measured by applying the test
signal into the AOUT_REF pin and measuring the resulting output amplitude on the AOUTx pin. Spec-
