3 Description

The TLV674x family includes single (TLV6741), dual

(TLV6742), and quad-channel (TLV6744) generalpurpose

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 smallsize

SC70-5 package. The dual-channel TLV6742 is

available in multiple package options including a tiny

1.5 mm × 2.0 mm X2QFN package.
