DAC ANALOG CHARACTERISTICS

Test conditions (unless otherwise specified): T

= 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-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. V

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.

9. 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-

ification calculated by:

10. Applying a DC voltage on the AOUT_REF pin will cause a DC offset on the DAC output. See Section

4.1.3 for more information.

COMBINED INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE

The filter characteristics have been normalized to the sample rate (Fs) and can be referenced to the desired sam-

ple rate by multiplying the given characteristic by Fs.

Notes: 11. Response is clock-dependent and will scale with Fs.

12. For Single- and Double-Speed Mode, the Measurement Bandwidth is from stopband to 3 Fs.

For Quad-Speed Mode, the Measurement Bandwidth is from stopband to 1.34 Fs.

13. De-emphasis is available only in Single-Speed Mode.

14. Amplitude vs. Frequency plots of this data are available in “Digital Filter Response Plots” on page 21.
