10. The maximum signal level at any input is defined as 3.17dB higher than the reference transmission level point.
11. Measured at 0TLP point for each gain setting. See Table 4 and Table 5.
12. 0TLP is the reference test level through inputs and outputs. See Table 4 and Table 5.
13. Referenced to 0TLP input at 1kHz, measured over 300 to 3,400 Hz bandwidth.
14. For die, only typical values from Analog Parameters are applicable.

All min/max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are
100 percent tested.
Low-frequency cut off depends upon the value of external capacitors (see Pin Descriptions).
Differential input mode. Nominal differential input is 208 mVp-p. (0 dBm0)
Sampling frequency can vary as much as –6/+4 percent over the industrial temperature and voltage ranges.
For greater stability, an external clock can be utilized (see Pin Descriptions). Sampling frequency will be accurate
within ±1% for 5.3kHz, and ±5% for 4.0, 6.4 and 8.0 kHz sampling rates at room temperature.
Playback and Record Duration can vary as much as –6/+4 percent over the industrial temperature and voltage
ranges. For greater stability, an external clock can be utilized (See Pin Descriptions). Playback and record durations
are accurate within ±1% for 5.3kHz, and ±5% for 4.0, 6.4 and 8.0kHz sampling rates at room temperature.
Filter specification applies to the low pass filter. Therefore, from input to output, expect a 6 dB drop by nature
of passing through the filter twice.
For optimal signal quality, this maximum limit is recommended.
When a record command is sent, T
(0TLP) This is the point where signal clipping may begin.
