Application notes
• Tuning in Amplifiers
Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier | Doc
• OPA320, OPA320S, OPA2320, OPA2320S EMI Immunity Performance | Doc
• Single-Supply Operation of Operational Amplifiers
Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation. | Doc
• Op Amp Performance Analysis
This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device | Doc

Features, Applications

OPAx320x Precision, 20-MHz, 0.9-pA, Low-Noise, RRIO, CMOS Operational Amplifier With Shutdown

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, singlesupply applications. Low-noise (7 nV/Hz) and highspeed 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 zerocrossover distortion that delivers excellent commonmode 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 mV of the rails. In addition, the OPAx320 has a wide supply voltage range from 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 5-pin SOT23 package; the OPA320S shutdown single version is available 6-pin SOT23 package. The dual OPA2320 is offered in 8-pin SOIC, VSSOP, and SON packages, and the OPA2320S (dual with shutdown) a 10-pin VSSOP package. Device Information(1) Block Diagram
