The TLV674x family includes single (TLV6741), dual (TLV6742), and quad-channel (TLV6744) general-purpose CMOS operational amplifiers (op amp) that provide a low noise figure of 3.5 nV/√Hz and a wide bandwidth of 10 MHz. The low noise and wide bandwidth make the TLV674x family of devices attractive for a variety of precision applications that require a good balance between cost and performance. Additionally, the input bias current of the TLV674x family supports applications with high source impedance.

The robust design of the TLV674x family provides ease-of-use to the circuit designer due to its unity-gain stability, integrated RFI/EMI rejection filter, no phase reversal in overdrive conditions and high electrostatic discharge (ESD) protection (2-kV HBM). Additionally, the resistive open-loop output impedance makes them easy to stabilize with much higher capacitive loads.

This op amp family is optimized for low-voltage operation as low as 2.25 V (±1.125 V) for the TLV6741 and 1.7 V (±0.85 V) for the TLV6742 and TLV6744. All of the devices operate up to 5.5 V (±2.75 V), and are specified over the temperature range of –40°C to 125°C.

The single-channel TLV6741 is available in a small-size SC70-5 package. The dual-channel TLV6742 is available in multiple package options including a tiny 1.5 mm × 2.0 mm X2QFN package.
