3 Description

The low-power TLV904x family includes single (TLV9041), dual (TLV9042), and quad-channel (TLV9044) ultra-low-voltage (1.2V to 5.5V) operational amplifiers (op-amps) with rail-to-rail input and output swing capabilities. The TLV904x enables power savings both with the low quiescent current (10µA, typical) and the ability to operate at supply voltages as low as 1.2V, making the device one of the few amplifiers in the industry capable of 1.5V coin cell applications. Further power savings can be achieved using the shutdown mode (TLV9041S, TLV9042S, and TLV9044S) that allows the amplifiers to be switched off and enter into a standby mode with typical current consumption of less than 150nA. These devices offer a cost-effective amplifier design for power and space-constrained applications such as battery-powered IoT devices, wearable electronics, and personal electronics where low-voltage operation is crucial.

The robust design of the TLV904x family simplifies circuit design. These op-amps feature an integrated RFI and EMI rejection filter, unity-gain stability, and no-phase reversal in input overdrive conditions. The device also delivers excellent AC performance with a gain bandwidth of 350kHz and a high cap load drive of 100pF, enabling designers to achieve both improved performance and lower power consumption.

Space-saving 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, VSSOP, TSSOP, and SOT-23 packages.
