LT1124/LT1125

Dual/Quad Low Noise,

High Speed Precision Op Amps

DescripTion

The

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

and I

than the OP-27; lower V

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.
