NOTES: (1) Works well for G < 10. Input offset causes output current to flow between amplifiers
with G > 10. Gains (resistor ratios) of the two amplifiers should be carefully matched to ensure
equal current sharing. (2) As configured (I
connected to V–) output current limit is set to 10A
(peak). Each amplifier is limited to 5A (peak). Other current limit values may be obtained, see
Figure 3, “Adjustable Current Limit”.
