DESCRIPTION
Dual/Quad 1.5MHz,
Rail-to-Rail, CMOS
Amplifi ers
The LTC
®
6084/LTC6085 are dual/quad, low cost, low offset,
rail-to-rail input/output, unity-gain stable CMOS operational
amplifi ers that feature 1pA of input bias current.
A 1.5MHz gain bandwidth, and 0.5V/s slew rate, along
with the wide supply range and a low 0.75mV offset, make
the LTC6084/LTC6085 useful in an extensive variety of ap-
plications from data acquisition to medical equipment and
consumer electronics. The 110A supply current and the
shutdown mode are ideal for signal processing applications
which demand performance with minimal power.
The LTC6084/LTC6085 have an output stage which swings
within 5mV 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 2.5V and
5V from –40°C to 125°C. The dual amplifi er LTC6084 is
available in 8-lead MSOP and 10-lead DFN packages. The
quad amplifi er LTC6085 is available in 16-lead SSOP and
DFN packages.
