3 Description

The TLV9051, TLV9052, and TLV9054 devices

are single, dual, and quad operational amplifiers,

respectively. The devices are designed for low voltage

operation from 1.8V to 6.0V. The inputs and outputs

can operate from rail to rail at a very high slew

rate. These devices are an excellent choice for costconstrained

applications where low-voltage operation,

high slew rate, and low quiescent current is needed.

The capacitive-load drive of the TLV905x family is

150pF, and the resistive open-loop output impedance

makes stabilization easier with much higher capacitive

loads.

The TLV905xS devices include a shutdown mode that

allow the amplifiers to be switched off into a standby

mode with typical current consumption less than 1μA.

The TLV905x family is easy to use due to the devices

being unity-gain stable, including a RFI and EMI filter,

and being free from phase reversal in an overdrive

condition.
