The output drives a 100Ω load to ±3.8V with ±5V supplies. On a single 5V supply, the output swings from 1V
to 4V with a 100Ω load connected to 2.5V. Harmonic
distortion is –70dB for a 5MHz, 2VP-P output driving a
100Ω load in a gain of –1.
The LT1815/LT1816/LT1817 are manufactured on Linear
Technology’s advanced low voltage complementary bipolar process and are available in a variety of SOT-23, SO,
MSOP, SSOP and leadless DFN packages.

■
The LT®1815/LT1816/LT1817 are low power, high speed,
very high slew rate operational amplifiers with excellent
DC performance. The LT1815/LT1816/LT1817 feature
higher bandwidth and slew rate, much lower input offset
voltage and lower noise and distortion than other devices
with comparable supply current. A programmable current
option (LT1815 and LT1816A) allows power savings and
flexibility by operating at reduced supply current and
speed. The circuit topology is a voltage feedback amplifier
with the slewing characteristics of a current feedback
amplifier.

The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C (Note 8). VS = 5V, 0V; VCM = 2.5V, RL to 2.5V unless otherwise noted.
For the programmable current option (LT1815S6 or LT1816A), the ISET pin must be connected to V – through 75Ω or less, unless
otherwise noted.

ISET Pin Current (Note 10)
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Differential inputs of ±6V are appropriate for transient operation
only, such as during slewing. Large sustained differential inputs can cause
excessive power dissipation and may damage the part.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 4: Input offset voltage is pulse tested and is exclusive of warm-up
drift.
Note 5: Slew rate is measured between ±2V at the output with ±3V input
for ±5V supplies and 2VP-P at the output with a 3VP-P input for single 5V
supplies.
Note 6: Full-power bandwidth is calculated from the slew rate:
FPBW = SR/2πVP.
Note 7: This parameter is not 100% tested.

Note 8: The LT1815C/LT1816C/LT1817C are guaranteed to meet specified
performance from 0°C to 70°C and are designed, characterized and
expected to meet the extended temperature limits, but are not tested at
– 40°C and 85°C. The LT1815I/LT1816I/LT1817I are guaranteed to meet
the extended temperature limits.
Note 9: Thermal resistance (θJA) varies with the amount of PC board metal
connected to the package. The specified values are for short traces
connected to the leads. If desired, the thermal resistance can be
substantially reduced by connecting Pin 2 of the SOT-23, Pin 4 of the
SO-8 and MS8, Pin 5 of the MS10 or the underside metal of the DD
package to a large metal area.
Note 10: A resistor of 40k or less is required between the ISET and V – pins
of the LT1815S6 and the LT1816AMS. See the applications section for
information on selecting a suitable resistor.

APPLICATIO S I FOR ATIO
Layout and Passive Components
As with all high speed amplifiers, the LT1815/LT1816/
LT1817 require some attention to board layout. A ground
plane is recommended and trace lengths should be minimized, especially on the negative input lead.
Low ESL/ESR bypass capacitors should be placed directly
at the positive and negative supply (0.01µF ceramics are
recommended). For high drive current applications, additional 1µF to 10µF tantalums should be added.
The parallel combination of the feedback resistor and gain
setting resistor on the inverting input combine with the
input capacitance to form a pole that can cause peaking or
even oscillations. If feedback resistors greater than 1k are
used, a parallel capacitor of value:
CF > RG • CIN/RF
should be used to cancel the input pole and optimize
dynamic performance. For applications where the DC
noise gain is 1 and a large feedback resistor is used, CF
should be greater than or equal to CIN. An example would
be an I-to-V converter.
Input Considerations
The inputs of the LT1815/LT1816/LT1817 amplifiers are
connected to the base of an NPN and PNP bipolar transistor in parallel. The base currents are of opposite polarity
and provide first-order bias current cancellation. Due to
variation in the matching of NPN and PNP beta, the
polarity of the input bias current can be positive or
negative. The offset current, however, does not depend
on beta matching and is tightly controlled. Therefore, the
use of balanced source resistance at each input is recommended for applications where DC accuracy must be
maximized. For example, with a 100Ω source resistance
at each input, the 800nA maximum offset current results
in only 80µV of extra offset, while without balance the 8µA
maximum input bias current could result in a 0.8mV offset
contribution.
The inputs can withstand differential input voltages of up
to 6V without damage and without needing clamping or
series resistance for protection. This differential input
voltage generates a large internal current (up to 80mA),
which results in the high slew rate. In normal transient
closed-loop operation, this does not increase power
dissipation significantly because of the low duty cycle of
the transient inputs. Sustained differential inputs, however, will result in excessive power dissipation and therefore this device should not be used as a comparator .
Capacitive Loading
The LT1815/LT1816/LT1817 are optimized for high bandwidth and low distortion applications. They can drive a
capacitive load of 10pF in a unity-gain configuration and
more with higher gain. When driving a larger capacitive
load, a resistor of 10Ω to 50Ω should be connected
between the output and the capacitive load to avoid ringing
or oscillation. The feedback should still be taken from the
output so that the resistor will isolate the capacitive load
to ensure stability.
Slew Rate
The slew rate of the LT1815/LT1816/LT1817 is proportional
to the differential input voltage. Therefore, highest slew rates
are seen in the lowest gain configurations. For example, a
5V output step in a gain of 10 has a 0.5V input step, whereas
in unity gain there is a 5V input step. The LT1815/LT1816/
LT1817 are tested for a slew rate in a gain of – 1. Lower
slew rates occur in higher gain configurations.
Programmable Supply Current
(LT1815/LT1816A)
In order to operate the LT1815S6 or LT1816A at full speed
(and full supply current), connect the ISET pin to the
negative supply through a resistance of 75Ω or less.
To adjust or program the supply current and speed of the
LT1815S6 or LT1816A, connect an external resistor (RSET)
between the ISET pin and the negative supply as shown in
Figure 1. The amplifiers are fully functional with 0 ≤ RSET
≤ 40k. Figures 2 and 3 show how the gain bandwidth and
supply current vary with the value of the programming
resistor RSET. In addition, the Electrical Characteristics
section of the data sheet specifies maximum supply
current and offset voltage, as well as minimum gain
bandwidth and output current at the maximum R SET value
of 40k.

The LT1815/LT1816/LT1817 combine high speed and
large output drive in small packages. It is possible to
exceed the maximum junction temperature specification
(150°C) under certain conditions. Maximum junction temperature (TJ) is calculated from the ambient temperature
(TA), power dissipation per amplifier (PD) and number of
amplifiers (n) as follows:

Power dissipation is composed of two parts. The first is
due to the quiescent supply current and the second is due
to on-chip dissipation caused by the load current. The worstcase load induced power occurs when the output voltage
is at 1/2 of either supply voltage (or the maximum swing
if less than 1/2 the supply voltage). Therefore PDMAX is:

PDMAX = (10V) • (11.5mA) + (2.5V)2/100Ω = 178mW
TJMAX = 85°C + (2 • 178mW) • (150°C/W) = 138°C

Figure 3. Supply Current vs RSET Programming Resistor
The LT1815/LT1816/LT1817 circuit topology is a true
voltage feedback amplifier that has the slewing behavior of
a current feedback amplifier. The operation of the circuit
can be understood by referring to the Simplified Schematic. Complementary NPN and PNP emitter followers
buffer the inputs and drive an internal resistor. The input
voltage appears across the resistor, generating current
that is mirrored into the high impedance node.
Complementary followers form an output stage that buffers the gain node from the load. The input resistor, input
stage transconductance and the capacitor on the high
impedance node determine the bandwidth. The slew rate
is determined by the current available to charge the gain
node capacitance. This current is the differential input
voltage divided by R1, so the slew rate is proportional to
the input step. Highest slew rates are therefore seen in the
lowest gain configurations.
