Summary

The OPAx328 family of high-speed, precision amplifiers, with the low input noise and ultra-low input bias current, makes them an excellent choice for the implementation of variety of different analog functions from communication to industrial applications. OPAx328 high gain-bandwidth, low noise and flat open-loop output impedance (Zo) are exceptionally well-suited for buffering of the reference voltages as well as driving high-resolution analog-to-digital converters (ADCs). At the same time, its ultra-low input bias current over wide temperature range makes OPAx328 an excellent choice for high input impedance, single-supply applications like the very high-gain trans-impedance amplifiers (TIA). This enables precision measurement of photo-currents down to hundreds of pico-amps (also, please see OPA3S328).
