LMC6024
Low Power CMOS Quad Operational Amplifier
General Description
The LMC6024 is a CMOS quad operational amplifier which
can operate from either a single supply or dual supplies. Its
performance features include an input common-mode range
that reaches V−, low input bias current and voltage gain (into
100 kΩ and 5 kΩ loads) that is equal to or better than widely
accepted bipolar equivalents, while the power supply re-
quirement is less than 1 mW.
This chip is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC6022 datasheet for a CMOS dual operational
amplifier with these same features.
Features
n Specified for 100 kΩ and 5 kΩ loads
n High voltage gain 120 dB
n Low offset voltage drift 2.5 µV/˚C
n Ultra low input bias current 40 fA
n Input common-mode range includes V−
n Operating range from +5V to +15V supply
n Low distortion 0.01% at 1 kHz
n Slew rate 0.11 V/µs
n Micropower operation 1 mW
Applications
n High-impedance buffer or preamplifier
n Current-to-voltage converter
n Long-term integrator
n Sample-and-hold circuit
n Peak detector
n Medical instrumentation
n Industrial controls
