40V Precision Low Power Operational Amplifiers
ISL28117, ISL28217
Features
• Low Input Offset . . . . . . . . . . . . . . ±50µV, Max.
• Superb Offset TC . . . . . . . . . . . . 0.6µV/°C, Max.
• Input Bias Current . . . . . . . . . . . . . . ±1nA, Max.
The ISL28117 and ISL28217 are a family of very high
precision amplifiers featuring low noise vs power
consumption, low offset voltage, low I
current and
BIAS
low temperature drift making 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.
• Input Bias Current TC . . . . . . . . . .±5pA/°C, Max.
• Low Current Consumption . . . . . . . . . . . . .440µA
• Voltage Noise. . . . . . . . . . . . . . . . . . . . . 8nV/Hz
• Wide Supply Range. . . . . . . . . . . . . . 4.5V to 40V
Applications for these amplifiers include precision active
filters, medical and analytical instrumentation, precision
power supply controls, and industrial controls.
• Operating Temperature Range . . -40°C to +125°C
• Small Package Offerings in Single and Dual
• Pb-Free (RoHS Compliant)
The ISL28117 single and ISL28217 dual are offered in an
8 Ld SOIC package. Both devices are offered in standard
pin configurations and operate over the extended
temperature range to -40°C to +125°C.
Applications*(see page 17)
• Precision Instruments
• Medical Instrumentation

1. Add “-T7” or “-T13” suffix for tape and reel. 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 ISL28117, ISL28217. For more information on
MSL please see techbrief TB363.

Applications Information
Functional Description
V+
The ISL28117 and ISL28217 are single and dual, low
noise precision op amps. Both devices are fabricated in a
new precision 40V complementary bipolar DI process. A
super-beta NPN input stage with input bias current
cancellation provides low input bias current (180pA
typical), low input offset voltage (13µV typical), low input
noise voltage (8nV/√Hz), and low 1/f noise corner
frequency (~8Hz). These amplifiers also feature high
open loop gain (18kV/mV) for excellent CMRR (145dB)

, 1kHz
RMS
The series resistors limit the high feed-through currents
that can occur in pulse applications when the input
dV/dT exceeds the 0.5V/µs slew rate of the amplifier.
Without the series resistors, the input can forward-bias
the anti-parallel diodes causing current to flow to the
output resulting in severe distortion and possible diode
failure. Figure 46 provides an example of distortion free
high capacitive load drive without external compensation.
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). The Power
Supply Rejection Ratio typically exceeds 140dB over the
full operating voltage range and 120dB minimum over
the -40°C to +125°C temperature range. The worst case
common mode input voltage range over temperature is
2V to each rail. With ±15V supplies, CMRR performance
is typically >130dB over-temperature. The minimum
CMRR performance over the -40°C to +125°C
large signal response using a 4V
input pulse with an
P-P
input rise time of <1ns. The series resistors enable the
input differential voltage to be equal to the maximum
power supply voltage (40V) without damage.
In applications where one or both amplifier input
terminals are at risk of exposure to high voltages beyond
the power supply rails, current limiting resistors may be
needed at the input terminal to limit the current through
the power supply ESD diodes to 20mA max.
temperature range is >120dB for power supply voltages
from ±5V (10V) to ±15V (30V).
Input Performance
Output Current Limiting
The super-beta NPN input pair provides excellent
frequency response while maintaining high input
precision. High NPN beta (>1000) reduces input bias
current while maintaining good frequency response, low
input bias current and low noise. Input bias cancellation
circuits provide additional bias current reduction to
<1nA, and excellent temperature stabilization. Figures 9
through 16 show the high degree of bias current stability
at ±5V and ±15V supplies that is maintained across the
-40°C to +125°C temperature range. The low bias
current TC also produces very low input offset current
TC, which reduces DC input offset errors in precision,
high impedance amplifiers.
The output current is internally limited to approximately
±45mA 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. Figures 25
and 26 show the current limit variation with temperature.
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 ISL28117 and ISL28217
are immune to output phase reversal, even when the
input voltage is 1V beyond the supplies.
The +25°C maximum input offset voltage (V ) for the
OS
“B” grade is 50µV and 100µV for the “C” grade. Input
offset voltage temperature coefficients (V TC) are a

maximum of ±0.6µV/°C for the “B” and ±0.9µV/°C for the
“C” grade. Figures 1 through 4 show the typical gaussian-
like distribution over the ±5V to ±15V supply range and
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

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:
constant TC across the entire temperature range.
Input ESD Diode Protection
The input terminals (IN+ and IN-) have internal ESD
protection diodes to the positive and negative supply
rails, series connected 500Ω current limiting resistors
and an anti-parallel diode pair across the inputs
(Figure 51).

DATE
REVISION
CHANGE
10/16/09
FN6632.2
On page 2 “Ordering Information”, changed the following:
a) corrected part marking for ISL28117FBBZ from "28117 -B FBZ" to "28117 FBZ -B".
Corrected part marking for ISL28217FBBZ from "28217-B FBZ" to "28217 FBZ -B"
B) Updated package outline drawing to most recent revision (no changes were made to
package dimensions; land pattern was added and dimensions were moved from table onto
drawing)
c) Added "Add “-T7” or “-T13” suffix for tape and reel." to the tape and reel Note 1.
d) added Note 3 callout to all parts (Note 3 reads: "For Moisture Sensitivity Level (MSL), please
see device information page for ISL28117, ISL28217. For more information on MSL please see
techbrief TB363.")
e) removed "Coming Soon" from ISL28117FBBZ, ISL28117FBZ & ISL28217FBBZ devices

FN6632.1
1. Removed “very” from “...low noise..” 1st sentence, page 1.
2. Removed “Low” from 6th bullet under features, page 1.
3. Modified typical characteristics curves to show conservative performance. Specific channel
designations removed. On temperature curves, changed formatting to indicate range from
typical value. Changes include:
a. Removed former Figures 1, 3, 5, 7, 9, 10, 13, 14, 17, 18, 21, 22, 25, 26, 29, 30, 33, 34,
37 & 38 (all Channel A curves)
b. Replaced former Figures 19, 20, 23, 24, 27, 28, 31, 32, 35, 36, 39 & 40 with new Figures
9 thru 20 (all “conservative channels”)
c. Added Figures 30, 31, 32
4. Updated TCVos histogram on page 1 to match TCVos histogram Figure 6 on page 7 (same
graphic)
5. Added temp labels to Figures 28 & 29
