Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are

determined from tested parameters.

NOTES TO THE ELECTRICAL SPECIFICATIONS

The electrical characteristics shown here apply to the specific test conditions shown above (see also Figure 1 in

description of the operation). The KH561 provides an equivalent, non-zero, output impedance determined by the

+10) is the no load gain. The actual gain to the matching 50

Ω load used in these specifications is half of this (+5).

The KH561 requires an external compensation capacitor. Unless otherwise noted, this has been set to 10.5pF for

the frequency domain specifications (yielding a maximally flat frequency response) and 12.5pF for the time domain

specifications (yielding a 0% small signal pulse overshoot response).
