Product details

Current-feedback topology means the slew rate stays nearly constant across gain settings — unlike voltage-feedback amps where higher gain cuts slew rate. That makes this part a fit for high-speed pulse amplification, video distribution, or ADC driver stages where a fast, clean edge matters across all four channels.

Quad-channel density in a tight footprint

Four amplifiers in a single 14-SOIC (3.90 mm width) body saves board area compared to stacking four single-channel parts.

Supply range and input characteristics

Operates from a 9 V to 22 V total supply span, so a single ±5 V or ±12 V rail works. Input bias current is 1.1 µA, input offset voltage 1.5 mV — typical for a current-feedback design.

The RoHS non-compliant status is the main sourcing constraint: if your BOM requires full lead-free compliance, this part won't pass. For designs that accept tin-lead solder (military, aerospace, or legacy industrial), the active status means stable supply through independent distribution.

Frequently asked questions

Is OPA4658UB RoHS compliant?

No, the OPA4658UB is listed as RoHS non-compliant. The leads contain lead (tin-lead finish), so it cannot be used in assemblies requiring full lead-free solder processes without an exemption.
