DESCRIPTION
Dual/Quad 14MHz,
Rail-to-Rail CMOS Amplifi ers
The LTC®6087/LTC6088 are dual/quad, low noise, low
offset, rail-to-rail input/output, unity-gain stable CMOS
operational amplifi ers that feature 1pA of input bias current. A 14MHz gain bandwidth and 7.2V/μs slew rate,
combined with low noise (10nV/√Hz) and a low 0.75mV
offset, make the LTC6087/LTC6088 useful in a variety of
applications. The 1.1mA supply current and the shutdown
mode are ideal for signal processing applications which
demand performance with minimal power.
The LTC6087/LTC6088 has an output stage which swings
within 30mV of either supply rail to maximize signal dynamic range in low supply applications. The input common
mode range includes the entire supply voltage. These op
amps are specifi ed on power supply voltages of 3V and
5V from –40°C to 125°C.
The dual amplifi er LTC6087 is available in 8-lead MSOP
and 10-lead DFN packages. The quad amplifi er LTC6088
is available in 16-lead SSOP and DFN packages.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: A heat sink may be required to keep the junction temperature
below the absolute maximum. This depends on the power supply voltage
and the total output current.
Note 3: The LTC6087C/LTC6088C are guaranteed functional over the
operating temperature range of –40°C to 85°C. The LTC6087H/LTC6088H
are guaranteed functional over the operating temperature range of –40°C
to 125°C.
Note 4: The LTC6087C/LTC6088C are guaranteed to meet specifi ed
performance from 0°C to 70°C. The LTC6087C/LTC6088C are designed,
characterized and expected to meet specifi ed performance from –40°C to
125ºC but are not tested or QA sampled at these temperatures.
The LTC6087H/LTC6088H are guaranteed to meet specifi ed performance
from –40°C to 125°C.
Note 5: ESD (electrostatic discharge) sensitive device. ESD protection
devices are used extensively internal to the LTC6087/LTC6088; however,
high electrostatic discharge can damage or degrade the device. Use proper
ESD handling precautions.
Note 6: This parameter is not 100% tested.
Note 7: This specifi cation is limited by high speed automated test
capability. See Typical Performance Characteristic curves for actual
performance.
Note 8: Current noise is calculated from:
i
n
= √2qIB,
where q = 1.6 • 10
–19
coulombs.
