THE HIGH GAIN AND WIDE BANDWIDTH OF THE LT1124/LT1125, IS USEFUL IN LOW
FREQUENCY HIGH CLOSED-LOOP GAIN AMPLIFIER APPLICATIONS. A TYPICAL
PRECISION OP AMP MAY HAVE AN OPEN-LOOP GAIN OF ONE MILLION WITH 500kHz
BANDWIDTH. AS THE GAIN ERROR PLOT SHOWS, THIS DEVICE IS CAPABLE OF 0.1%
AMPLIFYING ACCURACY UP TO 0.3Hz ONLY. EVEN INSTRUMENTATION RANGE
SIGNALS CAN VARY AT A FASTER RATE. THE LT1124/LT1125 “GAIN PRECISION —
BANDWIDTH PRODUCT” IS 75 TIMES HIGHER, AS SHOWN.

Table2summarizestheperformanceoftheLT1124/LT1125
compared to the low cost grades of alternate approaches.
The comparison shows how the specs of the LT1124/
LT1125 not only stand up to the industry standard OP-27,
but in most cases are superior. Normally dual and quad
performance is degraded when compared to singles, for
the LT1124/LT1125 this is not the case.
