Typical Performance Data www.ti.com
This section illustrates baseline PCM1691 performance on the DEM-DAI1691 with the defaultconfiguration. These data include typical performance versus sampling rate and system clock, and FFTresults for full-scale, –60 dB, –120 dB, and bipolar zero at 48 kHz/512 fS. As a result of a performancelimitation of the second-order active LPF and buffer for 2-VRMS out followed by the PCM1691 output, thereading performance is shown with 0.5-dB to 1.0-dB degradation in dynamic range, signal-to-noise ration(SNR), and channel separation.
Figure 3-1 shows typical PCM1691 performance versus the sampling rate and system clock.

If there are questionsconcerning the input range, please contact a TI field representative prior to connecting the input power.Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM.Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification,please contact a TI field representative.During normal operation, some circuit components may have case temperatures greater than +55°C. The EVM is designed to operateproperly with certain components above +55°C as long as the input and output ranges are maintained. These components include but arenot limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identifiedusing the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation,please be aware that these devices may be very warm to the touch.
