(OPA320-Q1, OPA2320-Q1) device is a new generation of precision low-voltage CMOS operational
amplifiers (op amps) optimized for very low noise and wide bandwidth and operate on a low quiescent
current of only 1.45 mA.
device is ideal for low-power, single-supply applications. Low-noise (7
nV/vHz) and high-speed operation also makes the device well-suited for
driving sampling analog-to-digital converters (ADCs). Other applications include signal
conditioning and sensor amplification.
device features 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 device has a wide supply voltage range from 1.8 to 5.5 V
with excellent PSRR (106 dB) over the entire supply range, making the device suitable for
precision, low-power applications that run directly from batteries without regulation.
device is available in an 8-pin VSSOP (DGK) package.
