3 Description

The LMV3xxA-Q1 family includes single (LMV321A-

Q1), dual (LMV358A-Q1), and quad-channel

(LMV324A-Q1) low-voltage (2.5 V to 5.5 V)

automotive operational amplifiers (op amps) with

rail-to-rail output swing capabilities. These op amps

provide a cost-effective method for space-constrained

applications such as infotainment and lighting where

low-voltage operation and high capacitive-load drive

are required. The capacitive-load drive of the

LMV3xxA-Q1 family is 500 pF, and the resistive open-

loop output impedance makes stabilization easier with

much higher capacitive loads. These op amps are

designed specifically for low-voltage operation (2.5 V

to 5.5 V) with performance specifications similar to the

LMV3xx-Q1 devices.

The robust design of the LMV3xxA-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.

The LMV3xxA-Q1 family is available in industry-

standard packages such as SOIC, MSOP, SOT-23,

and TSSOP packages.
