T he OP113 family dual operational amplifier features the lowest
noise and drift of any single-supply amplifier. It has been
designed for systems with internal calibration. Often these
processor based systems are capable of calibrating corrections
for offset and gain, but they cannot correct for temperature
drifts and noise. Optimized for these parameters, the OP113
family can be used to take advantage of superior analog perfor-
mance combined with digital correction. Many systems using
internal calibration operate from unipolar supplies, usually ei-
ther +5 volts or +12 volts. T he OP113 family is designed to op-
erate from single supplies from +4 volts to +36 volts, and to
maintain its low noise and precision performance.
T he OP113 family is unity gain stable and has a typical gain
bandwidth product of 3.4 MHz. Slew rate is in excess of 1 V/
μ
s.
Noise density is a very low 4.7 nV

, and noise in the 0.1 Hz
to 10 Hz band is 120 nV p-p. Input offset voltage is guaranteed
and offset drift is guaranteed to be less than 0.8

C. Input
common-mode range includes the negative supply and to within
1 volt of the positive supply over the full supply range. Phase re-
versal protection is designed into the OP113 family for cases
where input voltage range is exceeded. Output voltage swings
also include the negative supply and go to within 1 volt of the
positive rail. T he output is capable of sinking and sourcing cur-
rent throughout its range and is specified with 600
loads.
Digital scales and other strain gage applications benefit from the
very low noise and low drift of the OP113 family. Other appli-
cations include use as a buffer or amplifier for both A/D and
D/A sigma-delta converters. Often these converters have high
resolutions requiring the lowest noise amplifier to utilize their
full potential. Many of these converters operate in either single
supply or low supply voltage systems, and attaining the greater
signal swing possible increases system performance.
