6 Detailed Description

6.1 Overview

LMC6001-MIL has an extremely low input current of 25 fA. In addition, its ultra-low input current noise of 0.13

fA/√Hz allows almost noiseless amplification of high-resistance signal sources. LMC6001-MIL is ideally suited for

electrometer applications requiring ultra-low input leakage current such as sensitive photodetection

transimpedance amplifiers and sensor amplifiers.

6.3 Feature Description

6.3.1 Amplifier Topology

The LMC6001-MIL incorporates a novel op amp design topology that enables it to maintain rail-to-rail output

swing even when driving a large load. Instead of relying on a push-pull unity gain output buffer stage, the output

stage is taken directly from the internal integrator, which provides both low output impedance and large gain.

Special feed-forward compensation design techniques are incorporated to maintain stability over a wider range of

operating conditions than traditional op amps. These features make the LMC6001-MIL both easier to design with,

and provide higher speed than products typically found in this low-power class.

6.3.2 Latch-up Prevention

CMOS devices tend to be susceptible to latch-up due to their internal parasitic SCR effects. The (I/O) input and

output pins look similar to the gate of the SCR. There is a minimum current required to trigger the SCR gate

lead. The LMC6001-MIL is designed to withstand 100-mA surge current on the I/O pins. Some resistive method

should be used to isolate any capacitance from supplying excess current to the I/O pins. In addition, like an SCR,

there is a minimum holding current for any latch-up mode. Limiting current to the supply pins will also inhibit

latch-up susceptibility.

6.4 Device Functional Modes

The LMC6001-MIL has a single functional mode and operates according to the conditions listed in

Recommended Operating Conditions.
