OPAx320x Precision, 20-MHz, 0.9-pA, Low-Noise, RRIO, CMOS Operational Amplifier With Shutdown datasheet (Rev. 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. 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. 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 output voltage typically swings within 10 mV of the rails. ![]() The input common mode range extends 100 mV beyond the negative and positive supply rails. 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. Other applications include signal conditioning and sensor amplification. ![]() Low-noise (7 nV/√ Hz) and high- speed operation also make them well-suited for driving sampling analog-to-digital converters (ADCs). The OPA320 series is ideal for low-power, single- supply applications. 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.
