These devices operate on a low quiescent current of only 1.
45 mA.
The OPAx320-Q1 are an excellent choice for lowpower, single-supply applications.
Low-noise (7 nV/√Hz) and high-speed operation also makes these devices an excellent choice for driving sampling analog-to-digital converters (ADCs).
Other applications include signal conditioning and sensor amplification.
The OPAx320-Q1 feature a linear input stage with zero-crossover distortion that delivers excellent common-mode rejection ratio (CMRR) of 114 dB (typical) over the full input range.
The input commonmode range extends 100 mV beyond the negative and positive supply rails.
The output voltage typically swings within 10...
