GENERAL DESCRIPTION
The OPx13 family of single-supply operational amplifiers
features both low noise and drift. 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 OPx13 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 V or 12 V. The
OPx13 family is designed to operate from single supplies from
4 V to 36 V and to maintain its low noise and precision
performance.
The OPx13 family is unity gain stable and has a typical gain
bandwidth product of 3.4 MHz. Slew rate is in excess of 1 V/μs.
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 μV/°C. Input
common-mode range includes the negative supply and to
within 1 V of the positive supply over the full supply range.
Phase reversal protection is designed into the OPx13 family for
cases where input voltage range is exceeded. Output voltage
swings also include the negative supply and go to within 1 V of
the positive rail. The output is capable of sinking and sourcing
current throughout its range and is specified with 600 Ω loads.

Digital scales and other strain gage applications benefit from
the very low noise and low drift of the OPx13 family. Other
applications include use as a buffer or amplifier for both analog-
to-digital (ADC) and digital-to-analog (DAC) 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 OPx13 family is specified for single 5 V and dual ±15 V
operation over the XIND—extended industrial temperature
range (–40°C to +85°C). They are available in PDIP and SOIC
surface-mount packages.
