Application Hints
1.0 Input Common-Mode Voltage
Range
At supply voltages of 2.7V, 5V and 15V, the LMC6772 has an
input common-mode voltage range which exceeds both sup-
plies. As in the case of operational amplifiers, CMVR is de-
fined by the V
shift of the comparator over the
common-mode range of the device. A CMRR (
V
/
V
)
of 75 dB (typical) implies a shift of
<
1 mV over the entire
common-mode range of the device. The absolute maximum
input voltage at V
+
= 5V is 200 mV beyond either supply rail
at room temperature.
A wide input voltage range means that the comparator can
be used to sense signals close to ground and also to the
power supplies. This is an extremely useful feature in power
supply monitoring circuits.
An input common-mode voltage range that exceeds the sup-
plies, 20 fA input currents (typical), and a high input imped-
ance makes the LMC6772 ideal for sensor applications. The
LMC6772 can directly interface to sensors without the use of
amplifiers or bias circuits. In circuits with sensors which pro-
duce outputs in the tens to hundreds of millivolts, the
