Application Information
1.0 AMPLIFIER TOPOLOGY
The LMC6484 incorporates specially designed wide-compli-
ance range current mirrors and the body effect to extend input
common mode range to each supply rail. Complementary
paralleled differential input stages, like the type used in other
CMOS and bipolar rail-to-rail input amplifiers, were not used
because of their inherent accuracy problems due to CMRR,
cross-over distortion, and open-loop gain variation.
The LMC6484's input stage design is complemented by an
output stage capable of rail-to-rail output swing even when
driving a large load. Rail-to-rail output swing is obtained by
taking the output directly from the internal integrator instead
of an output buffer stage.
2.0 INPUT COMMON-MODE VOLTAGE RANGE
Unlike Bi-FET amplifier designs, the LMC6484 does not ex-
hibit phase inversion when an input voltage exceeds the
negative supply voltage. Figure 1 shows an input voltage ex-
ceeding both supplies with no resulting phase inversion on
the output.

FIGURE 1. An Input Voltage Signal Exceeds the LMC6484
Power Supply Voltages with No Output Phase Inversion
The absolute maximum input voltage is 300 mV beyond either
supply rail at room temperature. Voltages greatly exceeding
this absolute maximum rating, as in Figure 2, can cause ex-
cessive current to flow in or out of the input pins possibly
affecting reliability.
