APPLICATIONS

Battery-powered instrumentation Temperature transducer amplifier 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.

Rev. F | Page 13 of 24 The OP113, OP213, and OP413 form a new family of high performance amplifiers that feature precision performance in standard dual-supply configurations and, more importantly, maintain precision performance when a single power supply is used. In addition to accurate dc specifications, it is the lowest noise single-supply amplifier available with only 4.7 nV/√Hz typical noise density. Single-supply applications have special requirements due to the generally reduced dynamic range of the output signal. Single- supply applications are often operated at voltages of 5 V or 12 V , compared to dual-supply applications with supplies of ±12 V or ±15 V . This results in reduced output swings. Where a dual- supply application may often have 20 V of signal output swing, single-supply applications are limited to, at most, the supply range and, more commonly, several volts below the supply. In order to attain the greatest swing, the single-supply output stage must swing closer to the supply rails than in dual-supply applications. The OPx13 family has a new patented output stage that allows the output to swing closer to ground, or the negative supply, than previous bipolar output stages. Previous op amps had outputs that could swing to within about 10 mV of the negative supply in single-supply applications. However, the OPx13 family combines both a bipolar and a CMOS device in the output stage, enabling it to swing to within a few hundred μV of ground. When operating with reduced supply voltages, the input range is also reduced. This reduction in signal range results in reduced signal-to-noise ratio for any given amplifier. There are only two ways to improve this: increase the signal range or reduce the noise. The OPx13 family addresses both of these parameters. Input signal range is from the negative supply to within 1 V of the positive supply over the full supply range. Competitive parts have input ranges that are 0.5 V to 5 V less than this. Noise has also been optimized in the OPx13 family. At 4.7 nV/√Hz, the noise is less than one fourth that of competitive devices. PHASE REVERSAL The OPx13 family is protected against phase reversal as long as both of the inputs are within the supply ranges. However, if there is a possibility of either input going below the negative supply (or ground in the single-supply case), the inputs should be protected with a series resistor to limit input current to 2 mA. OP113 OFFSET ADJUST The OP113 has the facility for external offset adjustment, using the industry standard arrangement. Pin 1 and Pin 5 are used in conjunction with a potentiometer of 10 kΩ total resistance, connected with the wiper to V− (or ground in single-supply applications). The total adjustment range is about ±2 mV using this configuration. Adjusting the offset to 0 has minimal effect on offset drift (assuming the potentiometer has a tempco of less than 1000 ppm/°C). Adjustment away from 0, however, (as with all bipolar amplifiers) results in a TCV OS of approximately 3.3 μV/°C for every millivolt of induced offset. It is, therefore, not generally recommended that this trim be used to compensate for system errors originating outside of the OP113. The initial offset of the OP113 is low enough that external trimming is almost never required, but if necessary, the 2 mV trim range may be somewhat excessive. Reducing the trimming potentiometer to a 2 kΩ value results in a more reasonable range of ±400 μV .
