Product details

Wideband JFET op-amp for high-speed analog front-ends

The -3 dB bandwidth of 765 MHz supports video and communications links that need clean pulse response through the full small-signal passband. The JFET input stage provides the high input impedance and low noise floor that optical and sensor front-ends require, while the 110 mA output current per channel can drive ADCs or 50 Ω transmission lines directly. The supply range spans 6 V to 13 V, giving flexibility for single or split-rail designs without needing a separate high-voltage rail.

The 8-SON (3x3 mm) exposed-pad package helps pull heat out of the die when the part is running near its 26.5 mA supply current at high ambient temperatures.

The part comes in an 8-WFDFN exposed pad (supplier package 8-SON, 3x3 mm) for surface-mount assembly. The tape-and-reel and cut-tape options suit both prototyping and production reels.

Frequently asked questions

What is the closest functional equivalent for OPA818IDRGR?

The OPA859QDSGRQ1 is a JFET-input op-amp with a 900 MHz bandwidth and 1150 V/µs slew rate, qualified to AEC-Q100 for automotive use. It is a close parametric peer, though the OPA818IDRGR offers higher gain bandwidth (2.7 GHz) and a wider supply range.

Is OPA818IDRGR RoHS compliant?

Yes, the OPA818IDRGR is ROHS3 compliant, meeting the latest EU directive for lead-free and restricted-substance materials.

What does the 1400 V/µs slew rate mean for my design?

A 1400 V/µs slew rate means the output can swing from rail to rail in under 10 ns, which is necessary for amplifying fast pulses in time-of-flight lidar or wideband IF signals without slew-induced distortion. The 2.7 GHz GBP ensures the gain stays flat well into the VHF range.
