The LT1126 dual and LT1127 quad are high performance,
decompensated op amps that offer higher slew rate and
bandwidth than the LT1124 dual and the LT1125 quad
operational amplifiers. The enhanced AC performance 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,
particular 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.
