ISD1000A Series

1

NOTES: 1.

2.

All Min/Max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are 100% tested.

3.

Low-frequency cutoff depends upon value of external capacitors (see Pin Descriptions).

4.

From AUX IN; if ANA IN is driven at 50 mV p-p, the POUT= 12.2 mW, typical.

5.

With 5.1 K

Ω series resistor at ANA IN.

6.

This is the minimum pulse width required to guarantee that a Record cycle will be interrupted. A LOW-going PD pulse

of less than this interval during Record may be ignored.

7.

This is the minimum pulse width required to guarantee that a Playback cycle will be interrupted. A LOW-going PD pulse

of less than this interval during Playback may be ignored.

8.

This is the minimum pulse width required to reset the device when in a static condition; i.e., not actively recording or

playing back.

9.

Sampling Frequency and Playback Duration will vary as much as

±2.25% over the commercial temperature and voltage

range and

±5% over the industrial temperature and voltage range. For greater stability, an external clock can be utilized

(see Pin Descriptions).

10.

Filter specification applies to the antialiasing filter and to the smoothing filter.
