1. Typical values: T_A = 25°C and Vcc = 3.0V.
2. All min/max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are
100 percent tested.
3. Low-frequency cut off depends upon the value of external capacitors (see Pin Descriptions).
4. Differential input mode. Nominal differential input is 208 mVp-p. (0 dBm0)
5. 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.
6. 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.
7. 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.
8. For optimal signal quality, this maximum limit is recommended.
9. When a record command is sent, T_RAC = T_RAC + T_RACLO on the first row addressed.
10. The maximum signal level at any input is defined as 3.17dB higher than the reference transmission level point.
(0TLP) This is the point where signal clipping may begin.
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.
