open-in-new Find other General-purpose op amps

Description

The low-power TLV904x family includes single (TLV9041), dual (TLV9042), and quad-channel (TLV9044) low-voltage (1.2 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 power and space-constrained applications such as battery powered IoT devices, wearable electronics, and personal electronics where low-voltage operation and high capacitive-load drive are required. The capacitive-load drive of the TLV904x family is 70 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 (1.2 V to 5.5 V) which enables the full discharge of any battery chemistry.

The robust design of the TLV904x 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 TLV904x devices include a shutdown mode (TLV9041S, TLV9042S, and TLV9044S) that allow the amplifiers to switch off into standby mode with typical current consumption less than 1 µA.

Micro-size packages, such as X2QFN 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.
