Triple buffer for high-speed signal chains
The LT6554IGN#PBF from Analog Devices packs three independent voltage-feedback buffers into a single 16-SSOP package, each channel delivering 650 MHz small-signal bandwidth and a 2500 V/µs slew rate. Designed as a unity-gain buffer, it handles video distribution, ADC front-end drive, or any application needing a fast, low-distortion signal path through three channels. The wide single-supply range of 4.5V to 12V (or ±2.25V to ±6V dual) lets it run from common 5V or 12V rails without a separate negative supply.
Package and mounting
The 650 MHz -3dB bandwidth places this buffer in the class for high-resolution video (1080p, 4K, or RGB graphics) and fast-pulse amplification where settling time matters. The 2500 V/µs slew rate means the output can swing several volts in a few nanoseconds — critical for preserving the edges of digital video signals or driving the input of a high-speed ADC without slew-induced distortion. Together, these ratings tell you the part is built for signal integrity at frequencies where many general-purpose op-amps would roll off or slew-limit.
Three channels, one footprint
Three buffers in the 16-SSOP body save board area compared to three single amplifiers. Each channel operates independently with its own input and output, sharing only the supply and ground pins. The 8 mA total quiescent supply current is shared across all three buffers, keeping the thermal footprint modest — about 2.7 mA per channel. This makes the LT6554IGN#PBF a natural fit for multi-channel video or data-acquisition front-ends where per-channel power budgets are tight.
Active lifecycle and compliance
The 'IGN' suffix indicates the industrial temperature range version in the SSOP package; the commercial-grade sibling LT6554CGN#PBF shares the same die and performance but is specified over a narrower temperature window.
