LMC6492 Dual/LMC6494 Quad
CMOS Rail-to-Rail Input and Output Operational
Amplifier
General Description
The LMC6492/LMC6494 amplifiers were specifically devel-
oped for single supply applications that operate from −40˚C
to +125˚C. This feature is well-suited for automotive systems
because of the wide temperature range. A unique design
topology enables the LMC6492/LMC6494 common-mode
voltage range to accommodate input signals beyond the
rails. This eliminates non-linear output errors due to input
signals exceeding a traditionally limited common-mode volt-
age range. The LMC6492/LMC6494 signal range has a high
CMRR of 82 dB for excellent accuracy in non-inverting circuit
configurations.
The LMC6492/LMC6494 rail-to-rail input is complemented
by rail-to-rail output swing. This assures maximum dynamic
signal range which is particularly important in 5V systems.
Ultra-low input current of 150 fA and 120 dB open loop gain
provide high accuracy and direct interfacing with high imped-
ance sources.
