Texas Instruments TLV900x/TLV900x-Q1 Low-Voltage Op Amplifiers

Texas Instruments TLV900x/TLV900x-Q1 Low-Voltage Operational Amplifiers come with rail-to-rail input and output swing capabilities. These operational amplifiers provide a cost-effective solution for space-constrained applications. These applications include smoke detectors, wearable electronics, and small appliances, requiring low-voltage operation and high capacitive-load drive. The capacitive-load drive of the TLV900x is 500pF, and the resistive open-loop output impedance makes it easy to stabilize with much higher capacitive loads. These op amps are designed specifically for low-voltage operation (1.8V to 5.5V) with performance specifications similar to the TLV600x devices. The robust design of the Texas Instruments TLV900x simplifies the circuit design. These op amps feature unity-gain stability, an integrated RFI and EMI rejection filter, and no-phase reversal in overdrive conditions.
