The power dissipated in the package (PD) is the sum of the
quiescent power dissipation and the power dissipated by the
output stage transistor. It is calculated as follows:
PD = (VSY × ISY) + (VSY − VOUT) × ILOAD
where:
VSY is the power supply rail.
ISY is the quiescent current.
VOUT is the output of the amplifier.
ILOAD is the output load.
Do not exceed the 150°C maximum junction temperature for
the device. Exceeding the junction temperature limit can cause
degradation in the parametric performance or even destroy the
device. Refer to Technical Article MS-2251, Data Sheet Intricacies—

Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
MAXIMUM POWER DISSIPATION
The ADA4177-1, ADA4177-2, and ADA4177-4 can drive a
short-circuit output current of up to 65 mA. However, the
usable output load current drive is limited by the maximum
power dissipation allowed by the device package. The absolute
maximum junction temperature is 150°C (see Table 4). The
junction temperature can be estimated as follows:
Thermal resistance between junction and ambient (θJA) is
specified for the worst-case conditions, that is, a device soldered
in a circuit board for surface-mount packages.

The ADA4177-1, ADA4177-2, and ADA4177-4 are precision,
bipolar op amps that integrate both input overvoltage protection
(OVP) and input EMI filtering while maintaining a low 2 nA
maximum bias current and a rail-to-rail output operation.
Figure 84 shows a conceptual schematic of the main amplifier
that uses super beta, bipolar input transistors and bias current
cancellation to minimize the input bias current. The inputs are
cascoded to protect the super beta input devices from damage
during overvoltage conditions. The cascoded inputs feed into an
active load that makes up the primary gain stage. A buffered
transconductance (gm) stage converts a differential voltage to a
differential current to drive the output stage. The rail-to-rail
output can swing to 50 mV maximum (for example, the
guaranteed room temperature limit for VOH is 14.95 V when
the positive supply is 15 V) with a 1 mA load at 25°C.

APPLICATIONS INFORMATION
ACTIVE OVERVOLTAGE PROTECTION
Add External Clamping Diodes
The ADA4177-1/ADA4177-2/ADA4177-4 use active overvoltage
protection to protect the device from damage when the inputs
are driven to a voltage up to 32 V above the positive supply
voltage or 32 V below the negative supply voltage. The
ADA4177-1/ADA4177-2/ADA4177-4 not only protect the
input from damage, but they also reduce the input noise.
Precision op amps have a low offset voltage (VOS) and a high
common-mode rejection ratio (CMRR). Both of these
characteristics simplify system calibration and minimize
dynamic error. To maintain these specifications in the presence
of electrostatic discharge (ESD) events, bipolar op amps often
have internal clamp diodes and small limiting resistors in series
with their inputs; however, these do not address fault conditions
where the inputs exceed the rails. In these cases, the system
designer commonly adds clamping diodes (D1 and D2) along with
a series resistor (ROVP), as shown in Figure 86.
When an op amp does not have input overvoltage protection,
moving the input voltage above or below the supply voltage can
cause excessive input current, which can damage the op amp. To
avoid this, add a series resistor at the input. To protect the op
amp from a 30 V transient beyond either rail, limit the input
current to 5 mA, and add a 6 kΩ series resistor to the input.
However, a trade-off of adding the series resister is that it adds
thermal noise. The 6 kΩ series resistor exhibits 10 nV/√Hz of
thermal noise, which adds quadrature thermal noise from the
resistor with the op amp noise.
NTOTAL =
N OP AMP 2 + N RESISTOR 2
where:
NOP AMP is the op amp noise.
NRESISTOR is the thermal noise generated by the resistor.
When the additional thermal noise from the series resistor is
added to the thermal noise (8 nV/√Hz) of the ADA4177-1/
ADA4177-2/ADA4177-4, the 6 kΩ series resistor brings the
total thermal noise to 12 nV/√Hz, which is a 70% increase in
thermal noise. Figure 85 shows how noise from the additional
source resistance adds to the total noise at the amplifier input;
the higher the source resistance, the higher the total noise.
Because the ADA4177-1/ADA4177-2/ADA4177-4 have integrated input protection for overvoltage conditions, the noise
trade-off is avoided.

Figure 86. Common Scheme for Protecting Precision Amplifier Inputs from
Overvoltage Conditions
If the signal source at VIN is driven to one diode voltage beyond
the op amp supplies, the fault current is limited by ROVP. Schottky
diodes have a low forward knee voltage of 200 mV less than a
typical small signal diode. Therefore, all overvoltage currents
are shunted through the external diodes (D1 and D2). The reverse
leakage current for a typical Schottky diode is extremely variable
with the reverse voltage level. Therefore, as the noninverting
input of the op amp swings, the D1 and D2 leakage currents do
not match, and the differences pass through ROVP, creating a
voltage drop. The voltage drop on ROVP appears as a variation in
VOS, which can drastically reduce the CMRR performance.
Because the ADA4177-1/ADA4177-2/ADA4177-4 have integrated
input protection during overvoltage conditions, the degradation
in performance is avoided.

Data Sheet
J1A, J1B, J2A, and J2B are depletion mode junction field effect
transistors (JFETs) that replace the series resistance in the
conventional protection scheme. Under normal operation, the
input bias current of the ADA4177-1/ADA4177-2/ADA4177-4
flows through the J1A and J2A transistors without pinching off
the channel. To achieve excellent noise performance, J1A and
J2A must have a low on resistance (RDSON) of approximately
300 Ω.
When either input exceeds the rail by more than a diode, large
currents flow through either J1A or J2A, which causes the
channels to pinch off and effectively raises their resistance.
Figure 88 shows the positive overvoltage and negative
overvoltage characteristics as the FET channel pinches.
LIMITING OVERVOLTAGE CURRENT OUT OF THE
POSITIVE SUPPLY PIN
Because the positive power supply of the system may be incapable
of sinking the large overvoltage current of 8 mA (see Figure 88),
care was taken to divide down this current into the positive rail
during an overvoltage event. As shown in Figure 90, Q1L is a
lateral PNP transistor that serves two purposes. First, the
emitter base acts as a clamping diode to route the overvoltage
current away from the V+ pin and to the V− pin. Second, it
divides down this current via the beta of Q1L. At an emitter
current of 8 mA, the beta of Q1L is approximately 8, which
reduces the current injected into the positive supply by a factor
of 8.

Figure 91 shows the positive and negative supply currents when
the input voltage exceeds the supply voltages (and overvoltage
condition). The current at the V+ terminal does not reverse
direction during an overvoltage event because the current is
directed to V− via the collector of Q1L.

(a factor of 11).

USING THE ADA4177-1/ADA4177-2/ADA4177-4
AS A COMPARATOR
The ADA4177-1, ADA4177-2, and ADA4177-4 can be used as a
comparator as long as relatively small input impedance can be
tolerated. That is, the input differential pair is diode clamped
but the overvoltage protection circuitry limits the differential.

SELF HEATING
During an overvoltage condition, the ADA4177-1/ADA4177-2/
ADA4177-4 dissipate heat according to the thermal resistance
(θJA) of the package it is in, which, in turn, heats up the die. Ensure
that the specified operating junction temperature does not exceed
150°C for device protection. Extended overtemperature exposure
can cause some operating specifications to shift outside of their
guaranteed limits.
As shown in Figure 88, the ADA4177-1/ADA4177-2/ADA4177-4
inputs sink by approximately 8 mA at 15 V overvoltage. In that
condition, the ADA4177-1/ADA4177-2/ADA4177-4 dissipate
120 mW of power. If the package has a θJA of 100°C/W, the
junction temperature rises by approximately 12°C over the
ambient temperature of the package and junction. In such a case,
derate the ambient operating temperature by 12°C (125°C
minus 12°C) for an absolute maximum operating temperature
of 113°C. When the junction temperature exceeds the absolute
maximum junction temperature of 125°C, add an additional series

The ADA4177-1/ADA4177-2/ADA4177-4 inputs are also
protected from high frequency EMI. In an op amp with no EMI
protection, signals not within the bandwidth of the op amp
couple into sensitive amplifier inputs and become rectified as
they travel through the amplifier, eventually appearing as ac
feedthrough on top of a dc offset. When an input filter is not
provided, these offsets can be quite large. These offsets are
referred to as the electromagnetic interference rejection ratio
(EMIRR). The amplifier EMIRR is defined as
resistance to the inputs to further decrease the overvoltage
current. Figure 93 shows the maximum operating temperature vs.
the continuous overvoltage at θJA = 150°C/W.

positive and negative recovery is approximately 4 µs.

PROPER PRINTED CIRCUIT BOARD (PCB) LAYOUT
The ADA4177-1, ADA4177-2, and ADA4177-4 are high
precision devices. To ensure optimum performance at the PCB
level, take care in the design of the board layout.
To avoid leakage currents, maintain a clean and moisture free
board surface. Coating the surface creates a barrier to moisture
accumulation and reduces parasitic resistance on the board.

OUTPUT PHASE REVERSAL
Phase reversal is defined as a change in polarity in the amplifier
transfer function. Many op amps exhibit phase reversal when
the voltage applied to the input is greater than the maximum
common-mode voltage. In some instances, this phase reversal
can cause permanent damage to the amplifier. In feedback
loops, it can result in system lockups or equipment damage.
The ADA4177-1, ADA4177-2, and ADA4177-4 are immune to
phase reversal problems even at input voltages beyond the
power supply settings.
Keeping supply traces short and properly bypassing the power
supplies minimizes the power supply disturbances caused by
the output current variation, such as when driving an ac signal
into a heavy load. Connect bypass capacitors as closely as possible
to the device supply pins. Stray capacitances are a concern at the
outputs and the inputs of the amplifier. Keep the signal traces at
least 5 mm from supply lines to minimize coupling.
A variation in temperature across the PCB can cause a mismatch
in the Seebeck voltages at solder joints and other points where
dissimilar metals are in contact, resulting in thermal voltage errors.
To minimize these thermocouple effects, orient resistors so that
heat sources warm both ends equally. Ensure, where possible,
that input signal paths contain matching numbers and types of
components, to match the number and type of thermocouple
junctions. For example, dummy components such as zero value
resistors can be used to match real resistors in the opposite
input path. Place matching components in close proximity to
each other, and orient them in the same manner. Ensure that
leads are of equal length so that thermal conduction is in
equilibrium. Keep heat sources on the PCB as far away from
amplifier input circuitry as is practical.
The use of a ground plane is highly recommended. A ground
plane reduces EMI noise and maintains a constant temperature
across the circuit board.
