The OPA320-Q1 and OPA2320-Q1 (OPAx320-Q1) devices are a new generation of precision
low-voltage CMOS operational amplifiers (op amps) optimized for very low noise and wide bandwidth.
These devices operate on a low quiescent current of only 1.45 mA.
The OPAx320-Q1 are an excellent choice for low-power, 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 common-mode range extends 100 mV beyond the negative and positive supply rails. The output
voltage typically swings within 10 mV of the rails.
In addition, the OPAx320-Q1 have a wide supply voltage range from 1.8 V to 5.5 V, with
excellent PSRR (106 dB) over the entire supply range. These features make the OPAx320-Q1 suitable
for precision, low-power applications that run directly from batteries without regulation.
The OPAx320-Q1 device is available in an 8-pin VSSOP (DGK) package.
