Product details

What this differential driver brings to the signal chain

Its 400 MHz -3dB bandwidth and 6500V/µs slew rate mean it can handle high-resolution video (1080p and beyond), wideband instrumentation signals, or fast data links without rounding off the edges. The differential output helps reject common-mode noise picked up along the cable run, which is why you see this class of part in professional video distribution amplifiers, test equipment front-ends, and secure communication links where signal integrity matters.

Supply rails and drive capability — what to budget

That ±5V sweet spot is standard for video and RF stages, so it drops into existing ±5V analog rails without a separate regulator. Quiescent supply current is 46 mA, and each output can deliver 130 mA — enough to drive a 75 Ω terminated line to 2Vpp with headroom. If you are laying out a multi-channel board, budget 46 mA per device plus the load current; the 16-SOIC package with its 0.154" width keeps the footprint compact.

Package and mounting — surface-mount reality

It comes in a 16-SOIC (0.154", 3.90mm width) surface-mount package, supplier device package 16-SOIC. The tube shipping format is fine for prototype hand-assembly or low-volume production; if you need reel for pick-and-place, check the order code suffix (the ESE+ is tube). Standard SOIC footprint, no exposed pad — thermal management relies on the copper pour and vias under the body. For high-speed layout, keep the feedback and output traces short, and place 0.1 µF decoupling caps close to each supply pin.

Lifecycle and compliance — no end-of-life surprises

ROHS3 compliant, which covers the EU RoHS directive including the four phthalates.

Frequently asked questions
