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 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 1.05mA 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 dy-
namic range in low supply applications. The input common
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.
The dual amplifier LTC6087 is available in 8-lead MSOP
and 10-lead DFN packages. The quad amplifier LTC6088
is available in 16-lead SSOP and DFN packages.
