LTC6240/LTC6241/LTC6242

Single/Dual/Quad 18MHz,

Low Noise, Rail-to-Rail Output,

CMOS Op Amps

DESCRIPTION

The LTC

®

6240/6241/LTC6242 are single, dual and quad

low noise, low offset, rail-to-rail output, unity gain stable

CMOS op amps that feature 1pA of input bias current. Input

bias current is guaranteed to be 1pA max on the single

LTC6240. The 0.1Hz to 10Hz noise of only 550nV

P-P

, along

with an offset of just 125μV are signiﬁcant improvements

over 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 ±5V.

The LTC6240 is available in the 8-pin SO and the 5-pin SOT-

23 packages. The LTC6241 is available in the 8-pin SO, and

for compact designs it is packaged in a tiny dual ﬁne pitch

leadless (DFN) package. The LTC6242 is available in the

16-pin SSOP as well as the 5mm

×

3mm DFN package.
