- Rail-to-rail output swing enables maximum dynamic range in single-supply applications
- Wide supply voltage range: operates from 3V to 15V single supply or ±1.5V to ±7.5V dual supply
- CMOS voltage-feedback architecture with 63dB minimum CMRR (83dB typical)
- Available in Small Outline Package (SOIC) for compact PCB footprint
What is LMC662CM used for?
The LMC662CM is widely used in precision measurement and sensing applications such as photodiode amplifiers, pH electrode buffers, and electrometer-grade instrumentation where extremely low input leakage current is critical. Its rail-to-rail output and low-voltage operation make it suitable for battery-powered portable instruments, medical monitoring equipment, and data acquisition front-ends. The dual op-amp configuration also supports active filter designs and differential signal conditioning in industrial control systems.

Frequently Asked Questions
What is the input bias current of the LMC662CM?
The LMC662CM features an ultra-low input bias current of 2fA (femtoamperes) typical and 4fA maximum at 25°C, making it one of the lowest bias current op-amps available. This CMOS architecture virtually eliminates input leakage errors, which is essential for high-impedance sensor interfaces such as photodiodes, pH electrodes, and charge amplifiers.
What are the typical applications for the LMC662CM?
The LMC662CM is ideal for precision analog applications requiring minimal input loading, including photodiode transimpedance amplifiers, electrometer circuits, pH meter front-ends, medical biosensors, battery-powered portable instruments, and high-impedance data acquisition systems. Its rail-to-rail output and wide supply range (3V–15V single supply) make it versatile for both industrial and consumer designs.
What package does the LMC662CM come in and what does the 'M' suffix mean?
The LMC662CM is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The 'M' suffix in Texas Instruments' naming convention denotes the SOIC package. This surface-mount package offers a compact footprint of approximately 5mm × 4mm, suitable for space-constrained PCB designs.
Is there a pin-compatible replacement or alternative to the LMC662CM?
The LMC662CM (dual CMOS op-amp, SOIC-8) is pin-compatible with other standard dual op-amp packages. Close alternatives include the LMC6062 (precision CMOS), TLC272 (Texas Instruments CMOS dual op-amp), and ICL7642 from Renesas. Always verify supply voltage range, bandwidth (1.4MHz for LMC662CM), and input bias current specs before substituting in precision designs.
