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 com-
mon mode voltage range that includes ground. These fea-
tures, 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
n Improved latchup immunity
full-wave
rectifiers,
integrators,
references,
and
sample-and-hold circuits.
Applications
n Instrumentation amplifier
This device is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
n Photodiode and infrared detector preamplifier
n Transducer amplifiers
For designs with more critical power demands, see the
LMC6064 precision quad micropower operational amplifier.
n Medical instrumentation
n D/A converter
For a single or dual operational amplifier with similar fea-
tures, see the LMC6081 or LMC6082 respectively.
n Charge amplifier for piezoelectric transducers
