LTC6087/LTC6088
Dual/Quad 14MHz,
Rail-to-Rail CMOS Amplifiers
FEATURES
DESCRIPTION
The LTC®6087/LTC6088 are dual/quad, low noise, low
offset, rail-to-rail input/output, unity-gain stable CMOS
operational amplifiers that feature 1pA of input bias cur-
rent. 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.

mode range includes the entire supply voltage. These op
amps are specified on power supply voltages of 3V and
5V from –40°C to 125°C.
