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.
