The LT
®
1126 dual and LT1127 quad are high perfor-
mance, decompensated op amps that offer higher slew
rate and bandwidth than the LT1124 dual and the LT1125
quad operational amplifiers. The enhanced AC perfor-
mance is available without degrading DC specs of the
LT1124/LT1125. Both LT1126/LT1127 are stable in a gain
of 10 or more.
In the design, processing and testing of the device, par-
ticular attention has been paid to the optimization of the
entire distribution of several key parameters. Slew rate,
gain-bandwidth and 1kHz noise are 100% tested for each
individual amplifier. Consequently, the specifications of
even the lowest cost grades (the LT1126C and the LT1127C)
have been enhanced.
Power consumption of the dual LT1126 is less than one
half of two OP-37s. Low power and high performance in an
8-pin SO package makes the LT1126 a first choice for
surface mounted systems and where board space is
restricted.
