The 120 mA output current per channel drives cables or multiple ADC inputs directly, eliminating a separate buffer stage. A 2300 V/µs slew rate means the output can swing several volts in a nanosecond. For a 2 Vpp differential signal at 100 MHz, the required slew rate is roughly 630 V/µs, so this part has margin for large-signal handling without slew-induced distortion. That margin matters when driving the input of a high-speed ADC that expects a full-scale step and settles to 12-bit accuracy within one clock cycle. The current-feedback topology keeps the slew rate relatively independent of closed-loop gain, so you don't lose speed when setting gain with external resistors. ## Differential output — why it simplifies the receive chain The differential output directly interfaces to modern high-speed ADCs with differential inputs, avoiding an external balun or transformer. That saves board area and removes the insertion loss and phase imbalance a transformer introduces. The common-mode output voltage can be set independently via the VOCM pin, which lets the designer match the ADC's common-mode input range without extra level-shifting resistors. The 8-WSON (2.5x3) package with exposed pad keeps the thermal path short for the 29.1 mA quiescent current plus load current. ## Package and footprint considerations The package is surface-mount only, so hand-assembly prototypes need a hot-air rework station with a fine nozzle. ## Single-supply operation — what the voltage range allows The 4.5 V to 12 V supply span covers both single-supply (5 V or 12 V) and split-supply (±2.25 V to ±6 V) configurations. In single-supply mode with a 5 V rail, the output common-mode can be set to 2.5 V via the VOCM pin, centering the differential swing within the ADC's input range. The input common-mode range for a current-feedback amplifier is typically limited — the datasheet's common-mode voltage range should be checked against the input signal's DC bias. For a ground-referenced input, a DC-blocking capacitor and bias network are needed. ## Lifecycle and supply posture For production BOMs, this means no near-term LTB risk. The NOPB suffix indicates a lead-free (NiPdAu) finish, RoHS-compliant, with no Pb in the plating.","metaTitle":"LMH6553SD/NOPB Current Feedback Op-Amp, 900 MHz, 2300 V/µs","metaDescription":"TI LMH6553SD/NOPB current-feedback differential op-amp: 900 MHz -3 dB bandwidth, 2300 V/µs slew rate, 120 mA output, -40 to 125°C.

The 4.5 V minimum supply allows operation from a single 5 V rail. The VOCM pin sets the output common-mode voltage to mid-supply, enabling direct connection to single-supply ADCs.
