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 p F, 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.
