Rad Hard Dual 36V Precision Single-Supply, Rail-to-Rail
Output, Low-Power Operational Amplifiers
ISL70218SRH
Features
The ISL70218SRH is a dual, low-power precision amplifier
optimized for single-supply applications. This op amp features
a common mode input voltage range extending to 0.5V below
the V- rail, a rail-rail differential input voltage range, and
rail-to-rail output voltage swing, which makes it ideal for
single-supply applications where input operation at ground is
important.
• Wide Single and Dual Supply Range . . . . . . . .3V to 36V Max.
• Low Current Consumption . . . . . . . . . . . . . . . . . . 850µA, Typ.
• Low Input Offset Voltage. . . . . . . . . . . . . . . . . . . . . . 40µV, Typ.
• Rail-to-Rail Output . . . . . . . . . . . . . . . . . . . . . . . . . . . . . <10mV
• Rail-to-Rail Input Differential Voltage Range for Comparator
Applications
• Operating Temperature Range. . . . . . . . . . .-55°C to +125°C
• Below-ground (V-) Input Capability to -0.5V.
This op amp features low power, low offset voltage, and low
temperature drift, making it ideal for applications requiring
both high DC accuracy and AC performance. This amplifier is
designed to operate over a single supply range of 3V to 36V or a
split supply voltage range of +1.8V/-1.2V to ±18V. The
combination of precision and small footprint provides the user
with outstanding value and flexibility relative to similar
competitive parts.
• Low Noise Voltage . . . . . . . . . . . . . . . . . . . . . . 5.6nV/√Hz, Typ.
• Low Noise Current . . . . . . . . . . . . . . . . . . . . . .355fA/√Hz, Typ.
• Offset Voltage Temperature Drift. . . . . . . . . . . 0.3µV/°C, Typ.
• No Phase Reversal
• Radiation Tolerance
Applications for this amplifier include precision
instrumentation, data acquisition, precision power supply
controls, and industrial controls.
- High Dose Rate. . . . . . . . . . . . . . . . . . . . . . . . . . 100krad(Si)
- Low Dose Rate . . . . . . . . . . . . . . . . . . . . . . . . . . 100krad(Si)
- SEL/SEB LETTH (VS = ±18V) . . . . . . . . . . 86.4 MeV/mg/cm2
The ISL70218SRH is available in a 10 Ld hermetic ceramic
flatpack and operates over the extended temperature range of
-55°C to +125°C.

ISL70218SRH
Applications Information
Functional Description
R
F
V+
The ISL70218SRH is a dual, 3.2MHz, single-supply, rail-to-rail
output amplifier with a common mode input voltage range
extending to a range of 0.5V below the V- rail. The input stage is
optimized for precision sensing of ground-referenced signals in
single-supply applications. The input stage is able to handle large
input differential voltages without phase inversion, making this
amplifier suitable for high-voltage comparator applications. The
bipolar design features high open loop gain and excellent DC
input and output temperature stability. This op amp features very
low quiescent current of 850µA, and low temperature drift. The
device is fabricated in a new precision 40V complementary
bipolar DI process and is immune from latch-up for up to a 36V
supply range.

FIGURE 49. INPUT ESD DIODE CURRENT LIMITING
Output Drive Capability
The bipolar rail-to-rail output stage features low saturation levels
that enable an output voltage swing to less than 15mV when the
total output load (including feedback resistance) is held below
50µA (Figures 21 and 22). With ±15V supplies, this can be
achieved by using feedback resistor values >300kΩ.
Operating Voltage Range
The op amp is designed to operate over a single supply range of 3V
to 36V or a split supply voltage range of +1.8V/-1.2V to ±18V. The
device is fully characterized at 30V (±15V). Both DC and AC
performance remain virtually unchanged over the complete
operating voltage range. Parameter variation with operating
voltage is shown in the “Typical Performance Curves” beginning on
page 6.
The output stage is internally current limited. Output current limit
over temperature is shown in Figures 23 and 24. The amplifiers
can withstand a short circuit to either rail as long as the power
dissipation limits are not exceeded. This applies to only one
amplifier at a time for the dual op amp. Continuous operation
under these conditions may degrade long-term reliability.
The input common mode voltage to the V+ rail (V+ - 1.8V over the
full temperature range) may limit amplifier operation when
operating from split V+ and V- supplies. Figure 4 shows the
common mode input voltage range variation over temperature.
The amplifiers perform well when driving capacitive loads
(Figures 45 and 46). The unity gain, voltage follower (buffer)
configuration provides the highest bandwidth but is also the
most sensitive to ringing produced by load capacitance found in
BNC cables. Unity gain overshoot is limited to 35% at
capacitance values to 0.33nF. At gains of 10 and higher, the
device is capable of driving more than 10nF without significant
overshoot.
Input Stage Performance
The ISL70218SRH PNP input stage has a common mode input
range extending up to 0.5V below ground at +25°C. Full amplifier
performance is guaranteed for input voltage down to ground (V-)
over the -55°C to +125°C temperature range. For common mode
voltages down to -0.5V below ground (V-), the amplifiers are fully
functional, but performance degrades slightly over the full
temperature range. This feature provides excellent CMRR, AC
performance, and DC accuracy when amplifying low-level,
ground-referenced signals.
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 ISL70218SRH is immune to output phase reversal
out to 0.5V beyond the rail (VABS MAX) limit (Figure 38).
The input stage has a maximum input differential voltage equal
to a diode drop greater than the supply voltage and does not
contain the back-to-back input protection diodes found on many
similar amplifiers. This feature enables the device to function as
a precision comparator by maintaining very high input
impedance for high-voltage differential input comparator
voltages. The high differential input impedance also enables the
device to operate reliably in large signal pulse applications,
without the need for anti-parallel clamp diodes required on
MOSFET and most bipolar input stage op amps. Thus, input
signal distortion caused by nonlinear clamps under high slew
rate conditions is avoided.
Single Channel Usage
The ISL70218SRH is a dual op amp. If the application requires
only one channel, the user must configure the unused channel to
prevent it from oscillating. The unused channel oscillates if the
input and output pins are floating. This results in
higher-than-expected supply currents and possible noise
injection into the channel being used. The proper way to prevent
oscillation is to short the output to the inverting input, and
ground the positive input (Figure 50).
-
In applications in which one or both amplifier input terminals is
at risk of exposure to voltages beyond the supply rails,
current-limiting resistors may be needed at each input terminal
(see Figure 49, RIN+, RIN-) to limit current through the
power-supply ESD diodes to 20mA.

PDMAX for each amplifier can be calculated using Equation 2:
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:

NOTES:
1. Index area: A notch or a pin one identification mark shall be locat-
ed adjacent to pin one and shall be located within the shaded
area shown. The manufacturer’s identification shall not be used
as a pin one identification mark. Alternately, a tab (dimension k)
may be used to identify pin one.
2. If a pin one identification mark is used in addition to a tab, the lim-
its of dimension k do not apply.
3. This dimension allows for off-center lid, meniscus, and glass
overrun.
4. Dimensions b1 and c1 apply to lead base metal only. Dimension
M applies to lead plating and finish thickness. The maximum lim-
its of lead dimensions b and c or M shall be measured at the cen-
troid of the finished lead surfaces, when solder dip or tin plate
lead finish is applied.
5. N is the maximum number of terminal positions.
6. Measure dimension S1 at all four corners.
7. For bottom-brazed lead packages, no organic or polymeric mate-
rials shall be molded to the bottom of the package to cover the
leads.
8. Dimension Q shall be measured at the point of exit (beyond the
meniscus) of the lead from the body. Dimension Q minimum
shall be reduced by 0.0015 inch (0.038mm) maximum when sol-
der dip lead finish is applied.
9. Dimensioning and tolerancing per ANSI Y14.5M - 1982.
10. Controlling dimension: INCH.
