DESCRIPTION
The PA341 is a high voltage monolithic MOSFET operational amplifier which achieves performance fea‐
tures previously found only in hybrid designs while increasing reliability. Inputs are protected from excessive
common mode and differential mode voltages. The safe operating area (SOA) has no second breakdown lim‐
itation and can be observed with all type loads by choosing an appropriate current limiting resistor. External
compensation provides the user flexibility in choosing optimum gain and bandwidth for the application.
The PA341CE is packaged in a hermetically sealed 8‐pin TO‐3 package. The metal case of the PA341CE is
isolated in excess of full supply voltage.
The PA341DF is packaged in a 24 pin PSOP (JEDEC MO‐166) package. The metal heat slug of the PA341DF
is isolated in excess of full supply voltage.
The PA341DW is packaged in Apex Microtechnology’s hermetic ceramic SIP. The alumina ceramic isolates
the die in excess of full supply voltage.

SAFE OPERATING AREA (SOA)
The MOSFET output stage of the PA341 is not limited by second breakdown considerations as in bipolar
output stages. However there are still three distinct limitations:
1. Voltage withstand capability of the transistors.
2. Current handling capability of the die metalization.
3. Temperature of the output MOSFETS.
These limitations can be seen in the SOA (see Safe Operating Area graphs). Note that each pulse capabil‐
ity line shows a constant power level (unlike second breakdown limitations where power varies with voltage
stress). These lines are shown for a case temperature of 25°C and correspond to thermal resistances of 5.2°C/
W for the PA341CE and DF and 10.4°C/W for the PA341DW respectively. Pulse stress levels for other case
temperatures can be calculated in the same manner as DC power levels at different temperatures. The out‐
put stage is protected against transient flyback by the parasitic diodes of the output stage MOSFET structure.
However, for protection against sustained high energy flyback external fast‐recovery diodes must be used.

GENERAL
Please read Application Note 1 “General Operating Considerations” which covers stability, supplies, heat
sinking, mounting, current limit, SOA interpretation, and specification interpretation. Visit www.apexana‐
log.com for Apex Microtechnology’s complete Application Notes library, Technical Seminar Workbook, and
Evaluation Kits.
TYPICAL APPLICATION
Ref: APPLICATION NOTE 20: “Bridge Mode Operation of Power Amplifiers”
Two PA341 amplifiers operated as a bridge driver for a piezo transducer provides a low cost 660 V total
drive capability. The RN CN network serves to raise the apparent gain of A2 at high frequencies. If RN is set
equal to R the amplifiers can be compensated identically and will have matching bandwidths.
Figure 18: Typical Application (Low Cost 660 VP-P Piezo Driver)
PHASE COMPENSATION
Open loop gain and phase shift both increase with increasing temperature. The PHASE COMPENSATION
typical graph shows closed loop gain and phase compensation capacitor value relationships for four case
temperatures. The curves are based on achieving a phase margin of 50°. Calculate the highest case tempera‐
ture for the application (maximum ambient temperature and highest internal power dissipation) before
choosing the compensation. Keep in mind that when working with small values of compensation, parasitics
may play a large role in performance of the finished circuit. The compensation capacitor must be rated for at
least the total voltage applied to the amplifier and should be a temperature stable type such as NPO or COG.
OTHER STABILITY CONCERNS
There are two important concepts about closed loop gain when choosing compensation. They stem from
the fact that while “gain” is the most commonly used term, ß (the feedback factor) is really what counts when
designing for stability.
1. Gain must be calculated as a non‐inverting circuit (equal input and feedback resistors can provide a signal
gain of ‐1, but for calculating offset errors, noise, and stability, this is a gain of 2).
PA341U Rev D
13
PA341
2. Including a feedback capacitor changes the feedback factor or gain of the circuit. Consider RIN=4.7k,
RF=47k for a gain of 11. Compensation of 4.7 to 6.8pF would be reasonable. Adding 33pF parallel to the
47K rolls off the circuit at 103 kHz, and at 2 MHz has reduced gain from 11 to roughly 1.5 and the circuit is
likely to oscillate.
As a general rule the DC summing junction impedance (parallel combination of the feedback resistor and
all input resistors) should be limited to 5k ohms or less. The amplifier input capacitance of about 6pF, plus
capacitance of connecting traces or wires and (if used) a socket will cause undesirable circuit performance
and even oscillation if these resistances are too high. In circuits requiring high resistances, measure or esti‐
mate the total sum point capacitance, multiply by RIN/RF, and parallel RF with this value. Capacitors included
for this purpose are usually in the single digit pF range. This technique results in equal feedback factor calcu‐
lations for AC and DC cases. It does not produce a roll off, but merely keeps ß constant over a wide frequency
range. Paragraph 6 of Application Note 19 details suitable stability tests for the finished circuit.
CURRENT LIMIT
For proper operation, the current limiting resistor, RCL, must be connected as shown in Figure 2, “Typical
Connections”. The current limit can be predicted as follows:
V BE
I LIMIT A = ------------------R CL
The “VBE for ILIMIT” performance graph is used to find VBE. On this graph, the VBE+ and VBE− curves show
the voltages across the current limiting resistor at which current limiting is turned on. The VBE+ curve shows
these turn‐on voltages when the amplifier is sourcing current, and the VBE− curve shows these voltages when
the amplifier is sinking current.
The current limit can be thought of as a ceiling or limit for safe operation. For continuous operation it is
any value between the desired load current and 60 mA (as long as the curves on the SOA graph are not
exceeded, please refer to Safe Operating Area). As an example, suppose the desired load current for the
application is 20 mA. In this case we may set a current limit of 30 mA. Starting with the smaller VBE− of 0.6 we
have:
0.6V
R CL = ----------- = 20
1.03
For the larger VBE+ this RCL resistor will allow for a maximum current of:
0.7V
I LIMIT A = ----------- = 35mA
20
This value is still acceptable because it is less than 60 mA. For the case of continuous load currents, check
that the current limit does not exceed 60 mA.
The VBE values used above are approximate and can vary with process. To allow for this possibility the
user can reduce the VBE = 0.6 value by 20%. This results in a RCL value of 16 Ω. Using this same RCL value and
allowing for a 20% increase in the other VBE, the current limit maximum is 52 mA.
The absolute minimum value of the current limiting resistor is bounded by the largest current and the
largest VBE in the application. The largest VBE is determined by the coldest temperature in the application. In
general the largest VBE is VBE+ = 0.78V, which occurs at T = − 40°C. The largest allowed current occurs in
pulsed applications where, from the SOA graph, we can see current pulses of 120 mA. This gives us an abso‐
lute minimum RCL value of 0.78V/0.12 (A) = 6.5 Ω.

PA341
HEATSINKING
The PA341DF package has a large exposed integrated copper heatslug to which the monolithic amplifier
is directly attached. The solder connection of the heatslug to a minimum of 1 square inch foil area, on the
printed circuit board will result in thermal performance of 25°C/W junction to air rating of the PA341DF. Sol‐
der connection to an area of 1 to 2 square inches is recommended. This may be adequate heatsinking but the
large number of variables involved suggest temperature measurements be made on the top of the package.
Do not allow the temperature to exceed 85°C.
OVERVOLTAGE PROTECTION
Although the PA341 can withstand differential input voltages up to 16V, in some applications additional
external protection may be needed. Differential inputs exceeding 16V will be clipped by the protection cir‐
cuitry. However, if more than a few milliamps of current is available from the overload source, the protection
circuitry could be destroyed. For differential sources above 16V, adding series resistance limiting input cur‐
rent to 1mA will prevent damage. Alternatively, 1N4148 signal diodes connected anti‐parallel across the
input pins is usually sufficient. In more demanding applications where bias current is important, diode con‐
nected JFETs such as 2N4416 will be required. See Q1 and Q2 in Figure 19. In either case the differential input
voltage will be clamped to 0.7V. This is sufficient overdrive to produce the maximum power bandwidth.
In the case of inverting circuits where the +IN pin is grounded, the diodes mentioned above will also afford
protection from excessive common mode voltage. In the case of non‐inverting circuits, clamp diodes from
each input to each supply will provide protection. Note that these diodes will have substantial reverse bias
voltage under normal operation and diode leakage will produce errors.
Some applications will also need over‐voltage protection devices connected to the power supply rails.
Unidirectional zener diode transient suppressors are recommended. The zeners clamp transients to voltages
within the power supply rating and also clamp power supply reversals to ground. Whether the zeners are
used or not the system power supply should be evaluated for transient performance including power‐on
overshoot and power‐off polarity reversals as well as line regulation. See Z1 and Z2 in Figure 19.
