3 Description

The TLV900x family includes single (TLV9001), dual

(TLV9002), and quad-channel (TLV9004) 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 cost-effective solution

for space-constrained applications such as smoke

detectors, wearable electronics, and small appliances

where low-voltage operation and high capacitive-load

drive are required. The capacitive-load drive of the

TLV900x 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 devices.

The robust design of the TLV900x 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.

The TLV900x devices include a shutdown mode

(TLV9001S, TLV9002S, and TLV9004S) that allow the

amplifiers to switch off into standby mode with typical

current consumption less than 1 μA.

Micro-size packages, such as SOT-553 and WSON,

are offered for all channel variants (single, dual, and

quad), along with industry-standard packages such as

SOIC, MSOP, SOT-23, and TSSOP packages.
