LM221 LM321 Precision Preamplifiers February 1995 LM221 LM321 Precision Preamplifiers General Description The LM221 series are precision preamplifiers designed to operate with general purpose operational amplifiers to drastically decrease dc errors Drift bias current common mode and supply rejection are more than a factor of 50 better than standard op amps alone Further the added dc gain of the LM221 decreases the closed loop gain error The LM221 series operates with supply voltages from g 3V

Primary lithium battery LM 22150 3 V Primary lithium manganese dioxide (Li-MnO2) battery - - - - - - - - - - - - High power 1, 3 Sub C-size sprial cell For applications requiring excellent voltage response and operating life in -40°C, +70°C environment Benefits - High voltage response, stable during most of the life of the application - Minimal voltage delay after long dormant periods - Competitive capacity at high current and low temperature - Easy integration into compact systems - Low se
