Its 900 MHz -3 dB bandwidth and 2300 V/µs slew rate are the headline numbers for high-speed ADC driving, video distribution, and communications receivers where settling time and harmonic distortion matter. The current-feedback topology means the slew rate holds across the gain range, unlike voltage-feedback amps that trade speed for gain. Differential output directly interfaces with modern high-speed ADCs without an external balun, saving board area and bill-of-materials count. Supply range is 4.5 V to 12 V, and output can deliver 120 mA per channel — enough to drive a 50-ohm terminated line or a heavy capacitive load with care on the compensation. ## Package and thermal: the PowerPad matters Housed in an 8-PowerSOIC package (3.90 mm width, 0.154\" body) with an exposed thermal pad (PowerPad), this part relies on the pad being soldered to a copper plane for heat sinking. The 29.1 mA supply current at full bandwidth generates heat that the pad must carry; without a proper via stitch to a ground plane, junction temperature rises quickly under continuous drive. The supplier device package is 8-SO PowerPad, which is the same footprint as a standard SOIC-8 but with the pad underneath. Surface-mount assembly is straightforward with standard reflow profiles, but the pad requires a solder paste aperture in the stencil design — not a tombstone footprint. ## Sourcing and lifecycle: active, no LTB clock ticking The LMH6553MRE/NOPB carries an Active lifecycle status with ROHS3 compliance. There is no last-time-buy notice or obsolescence risk on the horizon. For volume production, the active status means no supply discontinuity — you can qualify it into a BOM without worrying about a sudden EOL notice. The NOPB suffix confirms lead-free (RoHS) finish, compatible with standard lead-free reflow profiles. ## Temperature grade and deployment environment Rated for -40°C to 125°C operating temperature, this amplifier suits industrial motor drives, outdoor telecom base stations, and automotive under-hood environments where the ambient can exceed 85°C. The extended range also covers avionics and downhole instrumentation that see wide thermal swings. The current-feedback architecture and differential output make it a natural fit for driving ADCs in data acquisition systems that must maintain accuracy across temperature.","metaTitle":"LMH6553MRE/NOPB Current-Feedback Op-Amp, 900 MHz, 2300 V/µs","metaDescription":"TI LMH6553MRE/NOPB current-feedback differential op-amp: 900 MHz -3 dB bandwidth, 2300 V/µs slew rate, 120 mA output.
