GENERAL DESCRIPTION
The OP113 family of single supply operational amplifiers fea-
tures both low noise and drift. It has been designed for sys-
tems 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 performance combined
with digital correction. Many systems using internal calibration
operate from unipolar supplies, usually either +5 volts or +12
volts. The OP113 family is designed to operate from single
supplies from +4 volts to +36 volts, and to maintain its low
noise and precision performance.
The 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/ s.
Noise density is a very low 4.7 nV/ Hz, 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 V/ C. Input
common-mode range includes the negative supply and to within
1 volt of the positive supply over the full supply range. Phase
reversal 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. The output is capable of sinking and sourcing
current throughout its range and is specified with 600
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.
The OP113 family is specified for single +5 volt and dual 15
volt operation over the XIND—extended industrial (–40 C to
+85 C) temperature range. They are available in plastic and
SOIC surface mount packages.
