LMC6032
CMOS Dual Operational Amplifier
General Description
The LMC6032 is a CMOS dual operational amplifier which
can operate from either a single supply or dual supplies. Its
performance features include an input common-mode range
that reaches ground, low input bias current, and high voltage
gain into realistic loads, such as 2 kΩ and 600Ω.
This chip is built with National’s advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC6034 datasheet for a CMOS quad operational
amplifier with these same features. For higher performance
characteristics refer to the LMC662.
Features
n Specified for 2 kΩ and 600Ω loads
