Texas Instruments LM290xLV/LM290xLV-Q1 Low Voltage Op Amps

Texas Instruments LM290xLV/LM290xLV-Q1 Low Voltage Operational Amplifiers include the dual LM2904LVLM2904LV-Q1 and quad LM2902LV/LM2902LV-Q1  operational amplifiers (op amps). These devices operate from a low voltage of 2.7V to 5.5V. These op amps supply an alternative to the LM2904 and LM2902 in low-voltage applications that are sensitive to cost. Some applications are large appliances, smoke detectors, and personal electronics. The LM290xLV/LM290xLV-Q1 devices have better performance than the LM290x devices at low voltage and lower power consumption. The op-amps are stable at unity gain and do not have a reverse phase in overdrive conditions. The design for ESD gives the LM290xLV/LM290xLV-Q1 family an HBM specification for a minimum of 2kV. The LM290xLV-Q1 devices are AEC-Q100 qualified for automotive applications.
