Preliminary Information

AC Gains Table - MH88510

‡ Typical figures are at 25

°C with nominal + 5V supplies and are for design aid only.

† AC Electrical Characteristics are over recommended operating conditions unless otherwise stated.

‡ Typical figures are at 25

°C with nominal + 5V supplies and are for design aid only.

Note1: All of the above test conditions use 754

Ω connected between JUNC and GRD, and 600W connected between Tip and Ring unless

otherwise stated.

Note 2: All of the above test conditions use 200Hz to 6400Hz unless otherwise stated.
