LMC6084
Precision CMOS Quad Operational Amplifier
General Description
Features
The LMC6084 is a precision quad low offset voltage opera-
tional amplifier, capable of single supply operation. Perfor-
mance characteristics include ultra low input bias current,
high voltage gain, rail-to-rail output swing, and an input
common mode voltage range that includes ground. These
features, plus its low offset voltage, make the LMC6084
ideally suited for precision circuit applications.
(Typical unless otherwise stated)
n Low offset voltage: 150 µV
n Operates from 4.5V to 15V single supply
n Ultra low input bias current: 10 fA
n Output swing to within 20 mV of supply rail, 100k load
n Input common-mode range includes V−
n High voltage gain: 130 dB
Other applications using the LMC6084 include precision full-
wave rectifiers, integrators, references, and sample-and-
hold circuits.
n Improved latchup immunity
Applications
This device is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
n Instrumentation amplifier
