Glossary of Terms

AGC Bias Current - The current drawn by the device from

the AGC voltage source, at maximum AGC voltage.

AGC Range - The total change in voltage gain (from

maximum gain to complete cutoff) which may be achieved by

application of the speciﬁed range of dc voltage to the AGC

input terminal of the device.

Common Mode Rejection Ratio - The ratio of the full

differential voltage gain to the common mode voltage gain.

Power Dissipation - The total power drain of the device with

no signal applied and no external load current.

Input Bias Current - The average value (one half the sum)

of the currents at the two input terminals when the quiescent

operating voltages at the two output terminals are equal.

Input Offset Current - The difference in the currents at the

two input terminals when the quiescent operating voltages at

the two output terminals are equal.

Input Offset Voltage - The difference in the DC voltages

which must be applied to the input terminals to obtain equal

quiescent operating voltages (zero output offset voltage) at

the output terminals.

Noise Figure - The ratio of the total noise power of the

device and a resistive signal source to the noise power of the

signal source alone, the signal source representing a

generator of zero impedance in series with the source

resistance.

Power Gain - The ratio of the signal power developed at

the output of the device to the signal power applied to the

input, expressed in dB.

Quiescent Operating Current - The average (DC) value of

the current in either output terminal.

Voltage Gain - The ratio of the change in output voltage at

either output terminal with respect to ground, to a change in

input voltage at either input terminal with respect to ground,

with the other input terminal at AC ground.
