Frequently Asked Questions

What is the input bias current of the LMC660CM?

The LMC660CM has an extremely low maximum input bias current (IIB) of 0.000002 µA (2 fA) at 25°C, making it ideal for high-impedance source applications such as pH sensors, photodiode amplifiers, and sample-and-hold circuits.

What package does the LMC660CM use?

The LMC660CM is housed in a Small Outline (SOIC) surface-mount package. It integrates four independent operational amplifiers in one IC, reducing board space compared to using discrete single or dual op-amp packages.

What are typical applications for the LMC660CM?

Typical applications include precision instrumentation front-ends, active low-pass and band-pass filters, electrochemical and biosensor signal conditioning, battery-powered portable instruments, and data acquisition systems that require minimal input loading and low offset error.

Can the LMC660CM replace other quad CMOS op-amps?

The LMC660CM is pin-compatible with industry-standard quad op-amp pinouts and can often replace other CMOS quad amplifiers such as the LMC6044 or TLC274 in designs that require lower bias current or improved CMRR performance. Always verify supply voltage and bandwidth requirements before substituting.
