DescripTion
The LT®1630/LT1631 are dual/quad, rail-to-rail input and
output op amps with a 30MHz gain-bandwidth product
and a 10V/µs slew rate.
n
Gain-Bandwidth Product: 30MHz
n
Slew Rate: 10V/µs
n
Low Supply Current per Amplifier: 3.5mA
n
Input Common Mode Range Includes Both Rails
The LT1630/LT1631 have excellent DC precision over the
full range of operation. Input offset voltage is typically
less than 150µV and the minimum open-loop gain of one
million into a 10k load virtually eliminates all gain error.
Tomaximizecommonmoderejection, theLT1630/LT1631
employ a patented trim technique for both input stages,
one at the negative supply and the other at the positive
supply, that gives a typical CMRR of 106dB over the full
input range.

Input Offset Voltage, Rail-to-Rail: 525µV Max
n
Input Offset Current: 150nA Max
n
Input Bias Current: 1000nA Max
n
Open-Loop Gain: 1000V/mV Min
n
Low Input Noise Voltage: 6nV/√Hz Typ
n
Low Distortion: –91dBc at 100kHz
n
Wide Supply Range: 2.7V to 15V
n
Large Output Drive Current: 35mA Min
n
TheLT1630/LT1631maintaintheirperformanceforsupplies
from 2.7V to 36V and are specified at 3V, 5V and 15V
supplies. The inputs can be driven beyond the supplies
withoutdamageorphasereversaloftheoutput.Theoutput
delivers load currents in excess of 35mA.

Active Filters
The LT1630 is available in 8-pin PDIP and SO packages
withthestandarddualopamppinout.TheLT1631features
the standard quad op amp configuration and is available
in a 14-pin plastic SO package. These devices can be used
as plug-in replacements for many standard op amps to
improve input/output range and performance.

Figure 1. LT1630 Simplified Schematic Diagram
To ensure that the LT1630/LT1631 are used properly,
calculate the worst-case power dissipation, get the ther-
mal resistance for a chosen package and its maximum
junction temperature to derive the maximum ambient
temperature.
Power Dissipation
The LT1630/LT1631 amplifiers combine high speed and
large output current drive in a small package. Because
the amplifiers operate over a very wide supply range, it
is possible to exceed the maximum junction temperature
of 150°C in plastic packages under certain conditions.
Example: An LT1630CS8 operating on 15V supplies and
driving a 500Ω, the worst-case power dissipation per
amplifier is given by:
Junction temperature, T , is calculated from the ambient
J
temperature, T , and power dissipation, P , as follows:
A
D
P
= (30V • 4.75mA) + (15V – 7.5V)(7.5/500)
LT1630CN8: T = T + (P • 130°C/W)

LT1631CS: T = T + (P • 150°C/W)

If both amplifiers are loaded simultaneously, then the
total power dissipation is 0.512W. The SO-8 package has
a junction-to-ambient thermal resistance of 190°C/W in
stillair. Therefore, themaximumambienttemperaturethat
the part is allowed to operate is:
The power dissipation in the IC is the function of the
supply voltage, output voltage and load resistance. For
a given supply voltage, the worst-case power dissipation

Input Offset Voltage
The LT1630/LT1631’s input stages are protected against
large differential input voltages by a pair of back-to-back
diodes D5/D6. When a differential voltage of more than
0.7V is applied to the inputs, these diodes will turn on,
preventingtheemitter-basebreakdownoftheinputtransis-
tors. The current in D5/D6 should be limited to less than
10mA. Internal 225Ω resistors R6 and R7 will limit the
input current for differential input signals of 4.5V or less.
For larger input levels, a resistor in series with either or
bothinputsshouldbeusedtolimitthecurrent.Worst-case
differentialinputvoltageusuallyoccurswhentheoutputis
shorted to ground. In addition, the amplifier is protected
against ESD strikes up to 3kV on all pins.
The offset voltage changes depending upon which input
stage is active, and the maximum offset voltages are
trimmed to less than 525µV. To maintain the precision
characteristics of the amplifier, the change of V over the
OS
entire input common mode range (CMRR) is guaranteed
to be less than 525µV on a single 5V supply.
Input Bias Current
The input bias current polarity depends on the input
common mode voltage. When the PNP differential pair is
active, the input bias currents flow out of the input pins.
They flow in the opposite direction when the NPN input
stage is active. The offset voltage error due to input bias
currents can be minimized by equalizing the noninverting
and inverting input source impedance.
Capacitive Load
The LT1630/LT1631 are wideband amplifiers that can
drive capacitive loads up to 200pF on 15V supplies in a
unity-gain configuration. On a 3V supply, the capacitive
load should be kept to less than 100pF. When there is a
need to drive larger capacitive loads, a resistor of 20Ω
to 50Ω should be connected between the output and the
capacitive load. The feedback should still be taken from
the output so that the resistor isolates the capacitive load
to ensure stability.
Output
The outputs of the LT1630/LT1631 can deliver large load
currents;theshort-circuitcurrentlimitis70mA.Takecareto
keep the junction temperature of the IC below the absolute
maximum rating of 150°C (refer to the Power Dissipation
section).Theoutputoftheseamplifiershavereverse-biased
diodestoeachsupply. Iftheoutputisforcedbeyondeither
supply, unlimited current will flow through these diodes.
If the current is transient and limited to several hundred
mA, no damage to the part will occur.
Feedback Components
The low input bias currents of the LT1630/LT1631 make it
possible to use the high value feedback resistors to set the
gain. However, care must be taken to ensure that the pole
formedbythefeedbackresistorsandthetotalcapacitanceat
theinvertinginputdoesnotdegradestability.Forinstance,
Overdrive Protection
To prevent the output from reversing polarity when the
input voltage exceeds the power supplies, two pairs of
crossing diodes D1 to D4 are employed. When the input
voltage exceeds either power supply by approximately
700mV, D1/D2 or D3/D4 will turn on, forcing the output
to the proper polarity. For this phase reversal protection
to work properly, the input current must be limited to less
than 5mA. If the amplifier is to be severely overdriven,
an external resistor should be used to limit the overdrive
current.
LT1630/LT1631 in a noninverting gain of 2, set with
the
two 20k resistors, will probably oscillate with 10pF total
input capacitance (5pF input capacitance and 5pF board
capacitance).Theamplifierhasa5MHzcrossingfrequency
and a 52° phase margin at 6dB of gain. The feedback
resistors and the total input capacitance form a pole at
1.6MHz that induces a phase shift of 72° at 5MHz! The
solution is simple: either lower the value of the resistors
or add a feedback capacitor of 10pF or more.

DC output level is set by the difference of the two inputs
multiplied by the gain of 100. Common mode range can
be calculated by the equations shown with Figure 2. For
example, the common mode range is from 0.15V to 2.65V
if the output is set at one half of the 3V supply. The com-
mon mode rejection is greater than 110dB at 100Hz when
trimmed with resistor R1. The amplifier has a bandwidth

up the DC level at the output. The Q factor can be adjusted
by varying the value of R8. The higher value of R8 will
decrease Q as depicted in Figure 5, because the output
induces less of feedback to amplifier A2. The value of R7
should be equal or greater than R9 to prevent oscillation.
If R8 is a short and R9 is larger than R7, then the positive

Typical applicaTion
RF Amplifier Control Biasing and DC Restoration
5V

R2
Taking advantage of the rail-to-rail input and output, and
the large output current capability of the LT1630, the
circuit, shown in Figure 6, provides precise bias currents
for the RF amplifiers and restores DC output level. To
ensure optimum performance of an RF amplifier, its bias
point must be accurate and stable over the operating
temperature range. The op amp A1 combined with Q1,
Q2, R1, R2 and R3 establishes two current sources of
21.5mA to bias RF1 and RF2 amplifiers. The current of
Q1 is determined by the voltage across R2 over R1, which
is replicated in Q2. These current sources are stable and
precise over temperature and have a low dissipated power
due to a low voltage drop between their terminals. The
amplifier A2 is used to restore the DC level at the output.
With a large output current of the LT1630, the output can
be set at 1.5VDC on 5V supply and 50Ω load. This circuit
has a 3dB bandwidth from 2MHz to 2GHz and a power
gain of 25dB.
