Texas Instruments TLV674x Low Power Operational Amplifier

Texas Instruments TLV674x Low Power Operational Amplifier (Op Amp) is a general-purpose CMOS op amp that provides low noise of 3.7nV/√Hz and a wide bandwidth of 10MHz. The low noise and wide bandwidth make the TLV674x attractive for various precision applications that require a good balance between cost and performance. Additionally, the input bias current of the device supports applications with high source impedance. The robust design of the Texas Instruments TLV674x provides ease of use to the circuit designer. This ease of use is due to its unity-gain stability, integrated RFI/EMI rejection filter, no phase reversal in overdrive conditions, and high electrostatic discharge (ESD) protection (1kV HBM). Additionally, the resistive open-loop output impedance makes it easy to stabilize with much higher capacitive loads.
