50 kHz gain-bandwidth — this is a DC-precision part, not an audio amp
The LMC6464BIM-TI is a Texas Instruments quad CMOS operational amplifier with a 50 kHz gain-bandwidth product and a 0.028 V/µs slew rate. Those numbers tell you immediately: this is a part designed for DC and very-low-frequency signal conditioning — think thermocouple amplifiers, strain-gauge bridges, photodiode front-ends, and battery-monitoring circuits. It is not meant for audio or any application where you need to swing a signal faster than a few hundred hertz. The rail-to-rail output stage lets you use the full supply range without losing headroom, which matters when running from a 3 V rail. The 90 µA total supply current for all four amplifiers makes it a strong candidate for loop-powered or battery-operated instruments where every microamp counts.
Input bias current: 0.15 pA — why it matters for sensor interfaces
With an input bias current of 0.15 pA, this op-amp can interface directly with high-impedance sources like photodiodes, pH electrodes, or piezoelectric sensors without needing a separate buffer stage. The 250 µV input offset voltage is respectable for a CMOS part at this price point, though not as tight as a precision bipolar amplifier. For a bridge sensor with a few millivolts of output, that offset is manageable with a software calibration or a trim pot.
Package and footprint
The supplier device package is 14-SOIC. Surface-mount assembly with standard reflow profiles; no special handling beyond normal MSL precautions.
Lifecycle and sourcing
The RoHS status is non-compliant, which means it contains lead (likely in the solder-dip terminations).
