The LT®1806 is a rail-to-rail input and output op amp that
features a 325MHz gain bandwidth product, a 140V/µs
slew rate and a 85mA output current to fit the need for low
voltage, high performance signal conditioning systems.
Gain Bandwidth Product: 325MHz
Slew Rate: 140V/µs
Wide Supply Range: 2.5V to 12V
Large Output Current: 85mA
Low Distortion, 5MHz: –80dBc
Low Voltage Noise: 3.5nV/√Hz
Input Common Mode Range Includes Both Rails
Output Swings Rail-to-Rail
Input Offset Voltage (Rail-to-Rail): 550µV Max
Common Mode Rejection: 106dB Typ
Power Supply Rejection: 105dB Typ
Open-Loop Gain: 300V/mV Typ
Power Down Pin
SO-8 Package
Operating Temperature Range –40°C to 85°C
The LT1806 has a very low distortion of – 80dBc at 5MHz,
a low input referred noise voltage of 3.5nV/√Hz and a
maximum offset voltage of 550µV that allows it to be used
in high performance data acquisition systems.
The LT1806 has an input range that includes both supply
rails and an output that swings within 20mV of either
supply rail to maximize the signal dynamic range in low
supply applications.
The LT1806 maintains its performance for supplies from
2.5V to 12V and is specified at 3V, 5V and ±5V supplies.
The inputs can be driven beyond the supplies without
damage or phase reversal of the output.

The LT1806 is available in an 8-pin SO package with the
standard op amp pinout. This device can be used as a plugin replacement for many op amps to improve input/output
range and performance.

Note 1: Absolute maximum ratings are those values beyond which the life
of the device may be impaired.
Note 2: The inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 1.4V, the input current should be limited to less than
10mA.
Note 3: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 4: The LT1806C/LT1806I are guaranteed functional over the
temperature range of –40°C and 85°C.
Note 5: The LT1806C is guaranteed to meet specified performance from
0°C to 70°C. The LT1806C is designed, characterized and expected to
meet specified performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. The LT1806I is guaranteed to meet
specified performance from –40°C to 85°C.
Note 6: Minimum supply voltage is guaranteed by power supply rejection
ratio test.
Note 7: Output Voltage swings are measured between the output and
power supply rails.
Note 8: This parameter is not 100% tested.
Note 9: Thermal resistance varies depending upon the amount of PC board
metal attached to Pin 4 of the device. θJA is specified for a 2500mm2 test
board covered with 2 oz copper on both sides.

APPLICATIO S I FOR ATIO
Single Supply Video Line Driver
The LT1806 is a wideband rail-to-rail op amp with high
output current that allows it to drive video signals in low
supply applications. The figure on the front page depicts
a single supply video line driver with AC coupling to
minimize the quiescent power dissipation. Resistors R1
and R2 are used to level-shift the input and output to
provide the largest signal swing. The gain of two is set up
with R3 and R4 to restore the signal at VOUT which is

attenuated by 6dB due to the matching of the 75Ω line with
the back-terminated resistor, R5. The back termination
will eliminate any reflection of the signal that comes from
the load. The input termination resistor, RT, is optional—
it is used only if matching of the incoming line is necessary. The values of C1, C2 and C3 are selected to minimize
the droop of the luminance signal. In some less stringent
requirements, the value of capacitors could be reduced.
