Description

The OPA320 (single) and OPA2320 (dual) are a new generation of precision, low-voltage CMOS operational amplifiers optimized for very low noise and wide bandwidth while operating on a low quiescent current of only 1.45 mA. The OPA320 series is ideal for low-power, single- supply applications. Low-noise (7 nV/√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. The OPA320 features a linear input stage with zero- crossover distortion that delivers excellent common- mode rejection ratio (CMRR) of typically 114 dB 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 has a wide supply voltage range from 1.8 V to 5.5 V with excellent PSRR (106 dB) over the entire supply range, making them suitable for precision, low-power applications that run directly from batteries without regulation. The OPA320 (single version) is available in a 5-pin SOT23 package; the OPA320S shutdown single version is available in an 6-pin SOT23 package. The dual OPA2320 is offered in 8-pin SOIC, VSSOP, and SON packages, and the OPA2320S (dual with shutdown) in a 10-pin VSSOP package.
