The OPA488, OPA2488, and OPA4488 (OPAx488) are 48V, wide-bandwidth, low noise, zero-drift operational amplifiers (op amps). The OPAx488 provides a pin compatible replacement to many industry standard amplifiers that can benefit from a higher operating voltage. The 48V operating voltage and the 60V absolute maximum enable robust circuit designs.

These op amps feature only 7.5µV of offset voltage (max) and 0.025µV/°C of offset voltage drift (max) over a wide temperature range. The OPAx488 feature very fast settling time due in part to the wide gain bandwidth and very high slew rate. The settling time is further enhanced in multichannel systems by the proprietary MUX-friendly input architecture.

The combination of high precision, fast settling, and low noise make the OPAx488 an excellent choice for a wide range of applications, including signal measurement, precision instrumentation, and data acquisition.

The OPAx488 are available in industry standard packages as well as micro-size packages to fit in the most space constrained applications. The devices are specified for operation from –40°C to +125°C.
