NOTES
1VREF = 5.00 V; conversion rate = 96 kSPS; fIN = 1.06 kHz; VIN = –0.05 dB unless otherwise noted. All measurements referred to a 0 dB (10 V p-p) input signal.
Values are post calibration.
2Includes first 19 harmonics.
3Minimum value of S/(N+D) corresponds to 5.0 V reference; typical values of S/(N+D) correspond to 10.0 V reference.
4fa = 1008 Hz; fb = 1055 Hz. See Definition of Specifications section and Figure 14.
5See Applications section for recommended voltage reference circuit and Figure 11 for performance with other reference voltage values.
6See Applications section for recommended input buffer circuit.
*For explanation of input characteristics, see “Analog Input” section.
Specifications subject to change without notice.
Specifications shown in boldface are tested on all devices at final electrical test at worst case temperature. Results from those tests are used to calculate outgoing
quality levels. All min and max specifications are guaranteed, although only those shown in boldface are tested.
