OPAx320/OPAx320-Q1 20MHz CMOS Op Amps

Texas Instruments OPAx320/OPAx320-Q1 20MHz CMOS Op Amps are optimized for very low noise and wide bandwidth while operating on a low quiescent current of only 1.45mA. TI OPAx320/OPAx320-Q1 op amps are ideal for low-power, single-supply applications. Low noise (7nV/√Hz) and high-speed operation also make them well-suited for driving sampling analog-to-digital converters (ADCs). Other applications include signal conditioning and sensor amplification. These TI op amps feature a linear input stage with zero-crossover distortion that delivers excellent common-mode rejection ratio (CMRR) of typically 114dB over the full input range. The input common-mode range extends 100mV beyond the negative and positive supply rails. The output voltage typically swings within 10mV of the rails.OPAx320/OPAx320-Q1 devices have a wide supply voltage range from 1.8V to 5.5V with excellent PSRR (106dB) over the entire supply range. The OPAx320-Q1 devices are AEC-Q100 qualified for automotive applications.
