Product details

What this current-feedback differential amp brings to the signal chain

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. 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.

The NOPB suffix confirms lead-free (RoHS) finish, compatible with standard lead-free reflow profiles.

The extended range also covers avionics and downhole instrumentation that see wide thermal swings.

Frequently asked questions

What is the bandwidth of LMH6553MRE/NOPB?

The -3 dB bandwidth is 900 MHz. Combined with the 2300 V/µs slew rate, this supports high-speed signal chains up to several hundred megahertz with good linearity.

What is a direct equivalent for LMH6553MRE/NOPB?

No pin-compatible direct equivalent is listed in the manufacturer's cross-reference. The THS4215DRBT is a voltage-feedback differential amp with 350 MHz bandwidth and 970 V/µs slew rate, but its voltage-feedback topology and lower speed make it a functional alternative only in lower-frequency designs that can tolerate the different compensation requirements.
