Intersil ISL28107SOICEVAL1Z Precision single and dual low noise operational amplifier Datasheet

ISL28107, ISL28207
Features
The ISL28107 and ISL28207 are single and dual
amplifiers featuring low noise, low input bias current, and
low offset and temperature drift. This makes them the
ideal choice for applications requiring both high DC
accuracy and AC performance. The combination of
precision, low noise, and small footprint provides the
user with outstanding value and flexibility relative to
similar competitive parts.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both
SnPb and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL28107 and ISL28207. For more information on
MSL please see techbrief TB363.

Applications Information
Functional Description
The ISL28107 and ISL28207 are single and dual, very
low 1/f noise (14nV/√Hz @ 10Hz) precision op-amps.
These amplifiers feature very high open loop gain
(50kV/mV) for excellent CMRR (145dB), and gain
accuracy. Both devices are fabricated in a new precision
40V complementary bipolar DI process.
The super-beta NPN input stage with bias current
cancellation provides bipolar-like levels of AC
performance with the low input bias currents
approaching JFET levels. The temperature stabilization
provided by bias current cancellation removes the high
input bias current temperature coefficient commonly
found in JFET amplifiers. Figures 7 and 8 show the input
bias current variation over temperature.
The input offset voltage (VOS) has an very low, worst
case value of 75µV max at +25°C and a maximum TC of
0.65µV/°C. Figure 36 shows VOS as a function of supply
voltage and temperature with the common mode voltage
at 0V for split supply operation.
The complimentary bipolar output stage maintains
stability driving large capacitive loads (to 10nF) without
external compensation. The small signal overshoot vs.
load capacitance is shown in Figure 52.
Output Current Limiting
The output current is internally limited to approximately
±40mA at +25°C and can withstand a short circuit to
either rail as long as the power dissipation limits are not
exceeded. This applies to only 1 amplifier at a time for
the dual op-amp. Continuous operation under these
conditions may degrade long term reliability.
Output Phase Reversal
Output phase reversal is a change of polarity in the
amplifier transfer function when the input voltage
exceeds the supply voltage. The ISL28107 and ISL28207
are immune to output phase reversal, even when the
input voltage is 1V beyond the supplies.
Using Only One Channel
The ISL28207 is a dual op-amp. If the application only
requires one channel, the user must configure the
unused channel to prevent it from oscillating. The unused
channel will oscillate if the input and output pins are
floating. This will result in higher than expected supply
currents and possible noise injection into the channel
being used. The proper way to prevent this oscillation is
to short the output to the inverting input and ground the
positive input (as shown in Figure 53).
-
Operating Voltage Range
The devices are designed to operate over the 4.5V
(±2.25V) to 40V (±20V) range and are fully
characterized at 10V (±5V) and 30V (±15V). Both DC
and AC performance remain virtually unchanged over the
complete 4.5V to 40V operating voltage range.
Parameter variation with operating voltage is shown in
the “Typical Performance Curves” beginning on page 6.
The input common mode voltage range sensitivity to
temperature is shown in Figure 36 (±15V).
Input ESD Diode Protection
The input terminals (IN+ and IN-) each have internal
ESD protection diodes to the positive and negative
supply rails, a series connected 500Ω current limiting
resistor followed by an anti-parallel diode pair across
the input NPN transistors (Circuit 1 in “Pin Descriptions”
on page 2).
The resistor-ESD diode configuration enables a wide
differential input voltage range equal to the lesser of the
Maximum Supply Voltage in the “Absolute Maximum
Ratings” on page 3 (42V) or, a maximum of 0.5V beyond
the V+ and V- supply voltage. The internal protection
resistors eliminate the need for external input current
limiting resistors in unity gain connections and other
circuit applications where large voltages or high slew
rate signals are present. Although the amplifier is fully
protected, high input slew rates that exceed the amplifier
slew rate (±0.32V/µs) may cause output distortion.

Power Dissipation
It is possible to exceed the +150°C maximum junction
temperatures under certain load and power supply
conditions. It is therefore important to calculate the
maximum junction temperature (TJMAX) for all
applications to determine if power supply voltages, load
conditions, or package type need to be modified to
remain in the safe operating area. These parameters are
related using Equation 1:
(EQ. 1)
T JMAX = T MAX + θ JA xPD MAXTOTAL
where:
• PDMAXTOTAL is the sum of the maximum power
dissipation of each amplifier in the package (PDMAX)
• PDMAX for each amplifier can be calculated using
Equation 2:
V OUTMAX
PD MAX = V S × I qMAX + ( V S - V OUTMAX ) × ---------------------------R

ISL28107, ISL28207 SPICE Model
Figure 54 shows the SPICE model schematic and
Figure 55 shows the net list for the ISL28107, ISL28207
SPICE model. The model is a simplified version of the
actual device and simulates important AC and DC
parameters. AC parameters incorporated into the model
are: 1/f and flatband noise, Slew Rate, CMRR, Gain and
Phase. The DC parameters are VOS, IOS, total supply
current and output voltage swing. The model uses
typical parameters given in the “Electrical
Specifications” Table beginning on page 3. The AVOL is
adjusted for 155dB with the dominate pole at 0.01Hz.
The CMRR is set (145dB, fcm = 100Hz). The input stage
models the actual device to present an accurate AC
representation. The model is configured for ambient
temperature of +25°C.

3/9/10
FN6631.2
1. Added MSOP package to the ordering information and added applicable POD M8.118 to end of
datasheet
2. Separated each part number with it's own specific -T7 and -T13 suffix. Removed “Add
“-T7” or “-T13” suffix for Tape and Reel.” from Note 1.
3. Added MSOP to the Pin Configuartion and Pin Descriptions
4. Updated ±15 and ±5V Electrical Specification table with the following edits:
A) Separated VOS specs for SOIC and MSOP packages. Added new VOS specs for MSOP Grade
package.
B) Separated TCVOS specs for SOIC and MSOP packages. Added new TCVOS specs for MSOP
package.
5. Added Theta JA and JC for the 8 Ld MSOP package. Added Theta JC values for both SOIC package
options. Changed Theta JA for 8 Ld SOIC (ISL28207) from 115 to 105.
2/22/10
1. Added “Related Literature*(see page 21)” on page 1.
2. Added Evaluation Boards to “Ordering Information” on page 2.
3. “Electrical Specifications” Tables, page 3 to page 6. Unbolded MIN/MAX specs with “TA = -40°C to
+85°C” conditions (since only MIN/MAX specs with “TA = -40°C to +125°C” conditions should be
bolded, per note in common conditions)
4. Corrected Note reference in ISC parameter on page 4 and page 5 from Note 3 to Note 7.
