The LMC6482IMMX/NOPB is a Texas Instruments dual CMOS rail-to-rail input and output operational amplifier in an 8-pin VSSOP package. The 20fA typical input bias current is among the lowest available for any op amp, making the LMC6482 ideal for high-impedance sensor interfaces such as photodiode transimpedance amplifiers, pH electrodes, and piezoelectric sensors where input bias current causes DC offset errors. The rail-to-rail input common-mode range extends to both supply rails, enabling direct interfacing with signals at ground or V+ in single-supply systems. The rail-to-rail output swings within 20mV of the supply rails with 100kohm load and within 1V with 600ohm load, maximizing dynamic range in low-voltage battery-powered applications. The 82dB CMRR and PSRR provide excellent accuracy in the presence of common-mode and supply noise. The 1.5MHz GBW and 1.3V/us slew rate support moderate-speed signal conditioning. The device is specified for 3V, 5V, and 15V operation, with performance guaranteed over the -40C to +85C temperature range. The LMC6482 is an improved replacement for the TLC272 and TLC277. The IMMX suffix indicates VSSOP-8 tape-and-reel, and NOPB indicates lead-free (Pb-free) finish.
