DescripTion
Dual/Quad Low Noise,
High Speed Precision Op Amps
The LT
®
1124 dual and LT1125 quad are high performance
op amps that offer higher gain, slew rate and bandwidth
than the industry standard OP-27 and competing OP-270/
OP-470 op amps. In addition, the LT1124/LT1125 have
lower I
B
and I
OS
than the OP-27; lower V
OS
and noise
than the OP-270/OP-470.
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 LT1124C and the
LT1125C) have been spectacularly improved compared
to equivalent grades of competing amplifiers.
Power consumption of the LT1124 is one-half of two
OP-27s. Low power and high performance in an 8-pin
SO package make the LT1124 a first choice for surface
mounted systems and where board space is restricted.
For a decompensated version of these devices, with three
times higher slew rate and bandwidth, please see the
LT1126/LT1127 data sheet.
