TYPICAL APPLICATION
Ref: Application Note 25
The high power bandwidth and high voltage output
of the MP38 allows driving ultra-sonic transducers
via a resonant circuit including the transducer and
a matching transformer. The load circuit appears
resistive to the MP38.

Please read Application Note 1 "General Operating Considerations" which covers stability, supplies, heat sinking,
mounting, current limit, SOA interpretation, and specification interpretation. Visit www.cirrus.com for design tools
that help automate tasks such as calculations for stability, internal power dissipation, current limit; heat sink selec-
tion; Apex’s complete Application Notes library; Technical Seminar Workbook; and Evaluation Kits.

CURRENT LIMIT
The two current limit sense lines are to be connected
directly across the current limit sense resistor. For the
current limit to work correctly pin 24 must be con-
nected to the amplifier output side and pin 23 con-
nected to the load side of the current limit resistor,
R CL , as shown in Figure 1. This connection will bypass
any parasitic resistances, Rp, formed by sockets and sol-
der joints as well as internal amplifier losses. The current
limiting resistor may not be placed anywhere in the output
circuit except where shown in Figure 1.
The value of the current limit resistor can be calculated
as follows:
