Product details

What this part is and where it fits

Supply range is 4.7 V to 5.25 V. Output current per channel is rated at 150 mA. Temperature range is -40°C to 125°C, so it can live in outdoor telecom enclosures, engine-bay electronics, or industrial instrumentation without derating.

2.8 GHz bandwidth and 6200 V/µs slew rate — what they mean for the design

Input offset voltage is 6.5 mV and input bias current is 1 µA — not a precision part, but that is expected for a current-feedback topology optimised for speed. If your signal chain needs microvolt-level offset, look at a JFET-input amplifier instead.

Lifecycle and sourcing

The LMH6554LE/NOPB is listed as Active and ROHS3 compliant. It is available through independent distribution and quoted to order against an RFQ.

Frequently asked questions

What is the LMH6554LE/NOPB's bandwidth and slew rate?

The -3 dB bandwidth is 2.8 GHz and the slew rate is 6200 V/µs.

Can the LMH6554LE/NOPB run on a single 5 V supply?

Yes, the supply span is 4.7 V to 5.25 V, so a single 5 V rail works.

What is an equivalent or replacement for LMH6554LE/NOPB?

The THS4215DRBT is a voltage-feedback alternative with 350 MHz bandwidth and 970 V/µs slew rate — a different topology, not a pin-for-pin swap. For a closer speed match, the OPA859QDSGRQ1 offers 900 MHz bandwidth and 1150 V/µs slew rate in a JFET-input design. Neither is a direct replacement; verify the pinout and compensation for your layout.
