Texas Instruments OPAx377/OPAx377-Q1 CMOS Operational Amplfiers
Texas Instruments OPAx377/OPAx377-Q1 CMOS Operational Amplifiers are single-, dual, and quad-channel wide-bandwidth CMOS amplifiers that provide very low noise, low input bias current, and low offset voltage while operating on a low quiescent current of 0.76mA. TI OPAx377/OPAx377-Q1 op amps are optimized for low-voltage, single-supply applications.
The exceptional combination of AC and DC performance make them ideal for a wide range of applications, including small signal conditioning, audio, and active filters. In addition, the TI OPAx377/OPAx377-Q1 have a wide supply range with excellent PSRR, making it attractive for applications that run directly from batteries without regulation. The OPAx377-Q1 devices are AEC-Q100 qualified for automotive applications.
