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

OS

shift of the comparator over the

common-mode range of the device. A CMRR (

∆V

OS/∆VCM)

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
