10 / 22 page Application Hints (Continued) TLH5609 – 9 c Single Supply Unipolar Output d Single Supply Bipolar Output FIGURE 1 Reference Connections (Continued) OUTPUTS The LM363’s output can typically swing within 1V of the supplies at light loads While specified to drivea2kX load to g10V current limit is typically 15 mA at room tempera- ture The output can stably drive capacitive loads up to 400 pF For higher load capacitance the amplifier may be overcompensated (see COMPENSATION section follow- ing) The output may be continuously shorted to ground without damaging the device OFFSET VOLTAGE The LM363’s offset voltage is internally trimmed to a very low value Note that data sheet values are given at Tje25 C VCMe0V and Va eVbe15V For other condi- tions warm-up drift temperature drift common-mode rejec- tion and power supply rejection must be taken into account Warm-up drift due to chip and package thermal gradients is an effect separate from temperature drift Typical warm-up drift is tabulated in the Electrical Characteristics settling time is approximately 5 minutes in still air At load currents up to 5 mA thermal feedback effects are negligible (DVOSs2mVatGe1000) Care must be taken in measuring the extremely low offset voltages of the high gain amplifiers Input leads must be held isothermal to eliminate thermocouple effects Oscilla- tions due to either heavy capacitive loading or stray capaci- tance from input to output can cause erroneous readings In either case overcompensation will help High frequency noise fed into the inputs may be rectified internally and pro- duce an offset shift A simple low-pass RC filter will usually cure this problem ( Figure 2 ) Use film type resistors for their low thermal EMF In highly noisy environments LC filters can be substituted for increased RF attenuation TLH5609 – 10 FIGURE 2 Low Pass Filter Prevents RF Rectification Instrumentation amplifiers have both an input offset voltage (VIOS) and an output offset voltage (VOOS) The total input- referred offset voltage (VOSRTI) is related to the instrumen- tation amplifier gain (G) as follows VOSRTIeVIOSaVOOS G The offset voltage given in the LM363 specifications is the total input-referred offset As long as only one gain is used offset voltage can be nulled at either input or output as shown in Figures 3a and 3b When the 16-pin device is used at multiple gain settings both VIOS and VOOS should be nulled to get minimum offset at all gains as shown in Figure 3c The correct procedure is to trim VOOS for zero output at Ge10 then trim VIOS at Ge1000 TLH5609 – 11 FIGURE 3 Offset Voltage Trimming 10 |
