62412f

Dual/Quad 18MHz, Low

Noise, Rail-to-Rail,

CMOS Op Amps

The LTC®6241/LTC6242 are dual and quad low noise,

low offset, rail-to-rail output, unity gain stable CMOS op

amps that feature 1pA of input bias current. The 0.1Hz to

10Hz noise of only 550nVP-P, along with an offset of just

125µV make them uncommon among traditional CMOS

op amps. Additionally, noise is guaranteed to be less

than 10nV/√Hz at 1kHz. An 18MHz gain bandwidth, and

10V/µs slew rate, along with the wide supply range and

low input capacitance, make them perfect for use as fast

signal processing ampliﬁers.

These op amps have an output stage that swings within

30mV of either supply rail to maximize the signal dynamic

range in low supply applications. The input common mode

range extends to the negative supply. They are fully speci-

ﬁed on 3V and 5V, and an HV version guarantees operation

on supplies up to ±5.5V.

The LTC6241 is available in the 8-pin SO, and for compact

designs it is packaged in the tiny dual ﬁne pitch leadless

(DFN) package. The LTC6242 is available in the 16-Pin

SSOP as well as the 5mm × 3mm DFN package.
