GENERAL D ESCRIP TIO N

T he 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. T he OP113 family is designed to operate 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/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 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. T he output is capable of sinking and sourcing

current throughout its range and is specified with 600 Ω loads.

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.

T he 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. T hey are available in plastic and

SOIC surface mount packages.

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

REV. C
