Supplied as a bare die (Supplier Device Package: Die), it is intended for hybrid, multi-chip module, or chip-on-board integration where a packaged SMD part would add footprint or parasitics. ## Supply range and output drive Operates from a single supply as low as 2.7 V up to 12.8 V max, covering common 3.3 V, 5 V, and 12 V rails without a split supply. Each output can source or sink 75 mA, enough to drive an ADC input or a 50-ohm back-terminated line with the rail-to-rail swing. Quiescent current is 2.7 mA per channel (10.8 mA total for all four), keeping the thermal budget low in dense die assemblies. ## Input offset and bias — what they mean for precision Input offset voltage is 1 mV typical, and input bias current is 1.6 µA — both moderate figures that suit AC-coupled or high-speed signal paths rather than DC-precise sensor front-ends. The 135 V/µs slew rate paired with the 130 MHz bandwidth means the part can reproduce a 10 Vpp sine wave up to about 21 MHz without slew-rate limiting, making it a fit for video or high-speed data acquisition. ## Active production, die-level sourcing The die form requires wire-bond or solder-bump assembly; no standard SMD package is offered for this order code, so verify your die-attach and bond-pad layout against the TI bonding diagram before committing the BOM. ## Where this class of part fits A quad voltage-feedback amplifier with rail-to-rail output and 130 MHz bandwidth fits into high-speed analog signal chains — ADC drivers, video distribution, or active filters in test equipment and communications infrastructure.","metaTitle":"TI LMH6644 MDC Voltage Feedback Op-Amp, 130 MHz, 135 V/µs","metaDescription":"Texas Instruments LMH6644 MDC quad voltage feedback op-amp, rail-to-rail output, 130 MHz bandwidth, 135 V/µs slew rate.
