Frequently Asked Questions
What is the input bias current of the LMC6494BEM?
The LMC6494BEM has a maximum average input bias current (IIB) of 0.0002 µA (200 pA), making it exceptionally suitable for high-impedance sensor interfaces such as pH electrodes, photodiodes, and capacitive pressure sensors where leakage current must be minimized.
What package does the LMC6494BEM use?
The LMC6494BEM is housed in a 14-lead SOIC (R-PDSO-G14) surface-mount package, which is lead-free (JESD-609 code e0) and suitable for automated PCB assembly. This compact package supports high-density board layouts in portable and space-constrained designs.
What are typical applications for the LMC6494BEM?
The LMC6494BEM is commonly used in battery-powered instruments, precision data acquisition front-ends, active filters, medical biosensing circuits, and industrial sensor signal conditioning. Its rail-to-rail I/O and 82 dB CMRR make it ideal wherever wide dynamic range and low noise are required.
Is the LMC6494BEM a rail-to-rail op-amp?
Yes, the LMC6494BEM features rail-to-rail input and output operation, meaning the input common-mode range extends to both supply rails and the output can swing to within millivolts of each rail. This maximizes usable signal range in single-supply and low-voltage applications.
