Texas Instruments  OPA320AQDBVRQ1

The OPAx320-Q1 (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.

The OPAx320-Q1 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.

The OPAx320-Q1 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.

The OPAx320-Q1 device is available in an 8-pin VSSOP (DGK) package.
