Often these processor-based Figure 3. 8-Lead PDIP Figure 4. 16-Lead Wide-Body systems are capable of calibrating corrections for offset and SOIC_W gain, but they cannot correct for temperature drifts and noise. Digital scales and other strain gage applications benefit from Optimized for these parameters, the OPx13 family can be used the very low noise and low drift of the OPx13 family. Other to take advantage of superior analog performance combined applications include use as a buffer or amplifier for both analog- with digital correction. Many systems using internal calibration to-digital (ADC) and digital-to-analog (DAC) sigma-delta operate from unipolar supplies, usually either 5 V or 12 V. The converters. Often these converters have high resolutions OPx13 family is designed to operate from single supplies from requiring the lowest noise amplifier to utilize their full 4 V to 36 V and to maintain its low noise and precision potential. Many of these converters operate in either single- performance. supply or low-supply voltage systems, and attaining the greater The OPx13 family is unity gain stable and has a typical gain signal swing possible increases system performance. bandwidth product of 3.4 MHz. Slew rate is in excess of 1 V/μs. The OPx13 family is specified for single 5 V and dual ±15 V Noise density is a very low 4.7 nV/√Hz, and noise in the 0.1 Hz operation over the XIND—extended industrial temperature to 10 Hz band is 120 nV p-p. Input offset voltage is guaranteed range (–40°C to +85°C). They are available in PDIP and SOIC and offset drift is guaranteed to be less than 0.8 μV/°C. Input surface-mount packages. 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.
