The LT

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.
