Power Operational Amplifier
DESCRIPTION
FEATURES
The MP111 operational ampliier is a surface mount
constructed component that provides a cost-effective
solution in many industrial applications. The MP111
offers outstanding performance that rivals much more
expensive hybrid components yet has a footprint of
only 4 sq in. The MP111 has many optional features
such as four-wire current limit sensing and external
compensation. The 500 kHz power bandwidth and 15
amp continuous and 50A pulse output of the MP111
makes it a good choice for piezo transducer drive applications. The MP111 is built on a thermally conductive but electrically insulating substrate that can be
mounted to a heat sink.

The speciication of MP111A is identical to the speciication for MP111 in the applicable column to the
left.
Unless otherwise noted: TC = 25°C, CC = 100pF. DC input speciications are value given. Power supply voltage is typical rating.
Long term operation at the maximum junction temperature will result in reduced product life. Derate
internal power dissipation to achieve high MTTF.
Doubles for every 10°C of case temperature increase.
+VS and -VS denote the positive and negative supply voltages to the output stage. +VB and -VB denote the positive and negative supply voltages to the input stages.
Rating applies if the output current alternates between both output transistors at a rate faster than
60Hz.
Power supply voltages +VB and -VB must not be less than +VS and -VS respectively.

GENERAL
Please read Application Note 1 "General Operating Considerations" which covers stability, power supplies, heat
sinking, mounting, current limit, SOA interpretation, and speciication interpretation. Visit www.cirrus.com for design
tools that help automate tasks such as calculations for stability, internal power dissipation, current limit, heat sink
selection, Apex Microtechnology's complete Application Notes library, Technical Seminar Workbook and Evaluation
Kits.
GROUNDPINS
The MP111 has two ground pins (pins 3, 32). These pins provide a return for the internal capacitive bypassing of
the small signal portions of the MP111. The two ground pins are not connected together on the substrate. Both of
these pins are required to be connected to the system signal ground.
SAFEOPERATINGAREA
The MOSFET output stage of the MP111 is not limited by second breakdown considerations as in bipolar output
stages. Only thermal considerations and current handling capabilities limit the SOA (see Safe Operating Area graph
on previous page). The output stage is protected against transient lyback by the parasitic body diodes of the output stage MOSFET structure. However, for protection against sustained high energy lyback external fast-recovery
diodes must be used.
COMPENSATION
The external compensation capacitor CC is connected between pins 5 and 6. Unity gain stability can be achieved
with any capacitor value larger than 100pF for a minimum phase margin of 45 degrees. At higher gains more phase
shift can usually be tolerated in most designs and the compensation capacitor value can be reduced resulting in
higher bandwidth and slew rate. Use the typical operating curves as a guide to select CC for the application. An
NPO (COG) type capacitor is required rated for the full supply voltage (100V).
OVERVOLTAGEPROTECTION
+Vs Z1
Although the MP111 can withstand differential input voltages up to ±25V, additional external protection is recommended. In most applications 1N4148 signal
diodes connected anti-parallel across the input pins is suficient. In more de+Vs

such as 2N4416 will be required. See Q1 and Q2 in Figure 1. In either case

Unidirectional zener diode transient suppressors are recommended. The zeners

overshoot and power-off polarity reversals as well as line regulation. See Z1
OVERVOLTAGEPROTECTION
and Z2 in Figure 1.
POWERSUPPLYBYPASSING
Bypass capacitors to power supply terminals +VS and -VS must be connected physically close to the pins to prevent
local parasitic oscillation in the output stage of the MP111. Use electrolytic capacitors at least 10µF per output amp
required. Bypass the electrolytic capacitors with high quality ceramic capacitors (X7R) 0.1µF or greater. In most
applications power supply terminals +Vb and -Vb will be connected to +VS and -VS respectively. Supply voltages
+Vb and -Vb are bypassed internally but both ground pins 3 and 32 must be connected to the system signal ground
to be effective. In all cases power to the buffer ampliier stage of the MP111 at pins 8 and 25 must be connected to
+Vb and -Vb at pins 4 and 30 respectively. Provide local bypass capacitors at pins 8 and 25. See the external connections diagram on page 1.

BOOSTOPERATION
With the boost feature the small signal stages of the ampliier are operated at a higher supply voltages than the
ampliier's high current output stage. +Vb (pins 4,8) and -Vb (pins 25,30) are connected to the small signal stages
and +VS (pins 14-16) and -VS (pins 17-19) are connected to the high current output stage. An additional 10V on the
+Vb and -Vb pins is suficient to allow the small signal stages to drive the output stage into the triode region and
improve the output voltage swing for extra eficient operation when required. When the boost feature is not needed
+VS and -VS are connected to the +Vb and -Vb pins respectively. The +Vb and -Vb pins must not be operated at
supply voltages less than +VS and -VS respectively.
BACKPLATEGROUNDING
The substrate of the MP111 is an insulated metal substrate. It is required that it be connected to signal ground.
Connect pin 2 (back plate) to signal ground. The back plate will then be AC grounded to signal ground through a
1µF capacitor.
