Offset null capability plus low input bias and off-set currents (8 nA and 1 nA respectively) minimize errors inboth high and low source impedance applications. Due toisothermal symmetry of the chip layout, gain is constant forloads 2k at output levels to 37V. Because of these fea-tures, the LM143 offers advantages not found in other gen-eral purpose op amps. The LM143 may, in fact, be used asan improved performance, plug-in replacement for theLM741 in most paper describes the operation of the LM143 and pre-sents applications which take advantage of its unique, highvoltage capabilities.
