Drives All Capacitive Loads
The LT1208/LT1209 are dual and quad very high speed
operational amplifiers with excellent DC performance. The
LT1208/LT1209 feature reduced input offset voltage and
higher DC gain than devices with comparable bandwidth
and slew rate. Each amplifier is a single gain stage with
outstanding settling characteristics. The fast settling time
makes the circuit an ideal choice for data acquisition
systems. Each output is capable of driving a 500Ω load to
±12V with ±15V supplies and a 150Ω load to ±3V on ±5V
supplies. The amplifiers are also capable of driving large
capacitive loads which make them useful in buffer or cable
driver applications.

Layout and Passive Components
Capacitive Loading
As with any high speed operational amplifier, care must be
taken in board layout in order to obtain maximum performance. Key layout issues include: use of a ground plane,
minimization of stray capacitance at the input pins, short
lead lengths, RF-quality bypass capacitors located close
to the device (typically 0.01µF to 0.1µF), and use of low
ESR bypass capacitors for high drive current applications
(typically 1µF to 10µF tantalum). Sockets should be
avoided when maximum frequency performance is required, although low profile sockets can provide reasonable performance up to 50MHz. For more details see
Design Note 50. The parallel combination of the feedback
resistor and gain setting resistor on the inverting input
combine with the input capacitance to form a pole which
can cause peaking. If feedback resistors greater than 5k
are used, a parallel capacitor of value
The LT1208/LT1209 amplifiers are stable with capacitive
loads. This is accomplished by sensing the load induced
output pole and adding compensation at the amplifier gain
node. As the capacitive load increases, both the bandwidth
and phase margin decrease so there will be peaking in the
frequency domain and in the transient response. The
photo of the small-signal response with 1000pF load
shows 50% peaking. The large-signal response with a
10,000pF load shows the output slew rate being limited by
the short-circuit current. To reduce peaking with capacitive loads, insert a small decoupling resistor between the
output and the load, and add a capacitor between the
output and inverting input to provide an AC feedback path.
Coaxial cable can be driven directly, but for best pulse
fidelity the cable should be doubly terminated with a
resistor in series with the output.
CF ≥ RG × CIN/RF
should be used to cancel the input pole and optimize
dynamic performance. For unity-gain applications where
a large feedback resistor is used, CF should be greater than
or equal to CIN.

caused by a second pole beyond the unity-gain crossover.
This is reflected in the 50° phase margin and shows up as
overshoot in the unity-gain small-signal transient response. Higher noise gain configurations exhibit less
overshoot as seen in the inverting gain of one response.
Small-Signal Capacitive Loading
AV = –1
CL = 1000pF
1208/09 AI01
The large-signal response in both inverting and noninverting gain show symmetrical slewing characteristics.
Normally the noninverting response has a much faster
rising edge due to the rapid change in input commonmode voltage which affects the tail current of the input
differential pair. Slew enhancement circuitry has been
added to the LT1208/LT1209 so that the falling edge slew
rate is balanced.

Input Considerations
Small-Signal Transient Response
Resistors in series with the inputs are recommended for
the LT1208/LT1209 in applications where the differential
input voltage exceeds ±6V continuously or on a transient
basis. An example would be in noninverting configurations with high input slew rates or when driving heavy
capacitive loads. The use of balanced source resistance at
each input is recommended for applications where DC
accuracy must be maximized.
Transient Response
The LT1208/LT1209 gain-bandwidth is 45MHz when measured at 100kHz. The actual frequency response in unitygain is considerably higher than 45MHz due to peaking

Power Dissipation
Large-Signal Transient Response
The LT1208/LT1209 combine high speed and large output
current drive in small packages. Because of the wide
supply voltage range, it is possible to exceed the maximum junction temperature under certain conditions.
Maximum junction temperature (TJ) is calculated from the
ambient temperature (TA) and power dissipation (PD) as
follows:
AV = 1

LT1208CN8:
LT1208CS8:

LT1209CS:
TJ = TA + (PD × 100°C/W)
TJ = TA + (PD × 150°C/W)
TJ = TA + (PD × 70°C/W)
TJ = TA + (PD × 100°C/W)
Maximum power dissipation occurs at the maximum
supply current and when the output voltage is at 1/2 of
either supply voltage (or the maximum swing if less than
1/2 supply voltage).
For each amplifier PDMAX is as follows:
PDMAX = (V + – V –)(ISMAX) +

1208/09 AI06
TJ = 70°C + (2 × 260mW)(150°C/W) = 148°C
Low Voltage Operation
DAC Current-to-Voltage Converter
The LT1208/LT1209 are functional at room temperature
with only 3V of total supply voltage. Under this condition,
however, the undistorted output swing is only 0.8VP-P . A
more realistic condition is operation at ±2.5V supplies (or
5V and ground). Under these conditions, at room temperature, the typical input common-mode range is 1.9V to
–1.3V (for a VOS change of 1mV), and a 5MHz, 2VP-P sine
wave can be faithfully reproduced. With 5V total supply
voltage the gain-bandwidth is reduced to 26MHz and the
slew rate is reduced to 135V/µs.
The wide bandwidth, high slew rate and fast settling time
of the LT1208/LT1209 make them well-suited for currentto-voltage conversion after current output D/A converters.
A typical application with a DAC-08 type converter (fullscale output of 2mA) uses a 5k feedback resistor. A 7pF
compensation capacitor across the feedback resistor is
used to null the pole at the inverting input caused by the
DAC output capacitance. The combination of the LT1208/
LT1209 and DAC settles to less than 40mV (1LSB) in
140ns for a 10V step.
