3 Description

The TLV900x-Q1 family includes single (TLV9001-

Q1), dual (TLV9002-Q1), and quad-channel

(TLV9004-Q1) low-voltage (1.8 V to 5.5 V) operational

amplifiers (op amps) with rail-to-rail input and output

swing capabilities. These op amps provide a costeffective

solution for space-constrained automotive

applications such as infotainment and lighting where

low-voltage operation and high capacitive-load drive

are required. The capacitive-load drive of the

TLV900x-Q1 family is 500 pF, and the resistive openloop

output impedance makes stabilization easier with

much higher capacitive loads. These op amps are

designed specifically for low-voltage operation (1.8 V

to 5.5 V) with performance specifications similar to the

TLV600x-Q1 devices.

The robust design of the TLV900x-Q1 family simplifies

circuit design. The op amps feature unity-gain

stability, an integrated RFI and EMI rejection filter, and

no-phase reversal in overdrive conditions.
