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

ThinSOT™ Package and 8-Pin SO for PCB Guard Ring

Dual LTC6241 in 8-Pin SO and Tiny DFN Packages

Quad LTC6242 in 16-Pin SSOP and 5mm × 3mm

DFN Packages

These op amps have an output stage that swings within

30mV of either supply rail to maximize the signal dynamic

rangeinlowsupplyapplications.Theinputcommonmode

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.

TheLTC6240isavailableinthe8-pinSOandthe5-pinSOT-

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.
