LMC6462AIMX

LMC6462AIMX Description

The LMC6462AIMX from Texas Instruments is a dual CMOS operational amplifier designed for low-power, precision applications. Operating within a 3V to 15.5V supply range, it delivers exceptional performance with an ultra-low input bias current of 0.15 pA and a gain bandwidth product of 50 kHz. Its 250 µV input offset voltage ensures high accuracy, while the 0.028V/µs slew rate and 75 mA output current per channel make it suitable for driving moderate loads. Packaged in an 8-SOIC tape & reel (TR), this obsolete but reliable IC remains a viable choice for legacy designs requiring stable, low-power amplification.

LMC6462AIMX Features

• Ultra-Low Power: Consumes only 50µA per channel, ideal for battery-operated systems.
• CMOS Technology: Ensures minimal power dissipation and high input impedance.
• Wide Supply Range: 3V to 15.5V operation accommodates diverse power sources.
• Low Input Bias Current: 0.15 pA minimizes errors in high-impedance circuits.
• Robust Output Drive: 75 mA/channel supports capacitive or resistive loads.
• Surface-Mount Package: 8-SOIC (TR) for compact PCB designs.

LMC6462AIMX Applications

• Sensor Interfaces: Precision signal conditioning for photodiodes, pH probes, and piezoelectric sensors.
