LM221 preamplifiers equivalent, lm221/lm321 precision preamplifiers.
Y Y Y Y Y Y Y
Guaranteed drift of LM321A 0 2 mV C Guaranteed drift of LM221 series 1 mV C Offset voltage less than 0 4 mV Bias current less than 10 nA at 10 mA operating.
where low bias current is more important than drift the operating current can be reduced to low values High operating cu.
