Product details

Package and mounting

It runs rail-to-rail on the output side, which matters when you are swinging close to the supply rails in a single-supply signal chain. The 3.3 mA per-channel supply current is the price you pay for that speed — this is not a micropower part, it is a signal-conditioning amp for ADC drivers, video buffers, or high-speed filter stages where bandwidth and settling time drive the choice.

Package and rework — the 8-DFN exposed pad

The 8-WFDFN exposed pad package (3x3 mm body) is a QFN-style part with a center thermal pad. That pad needs a via stitch to the ground plane to pull heat out of the die — without it the junction climbs fast if you push the 30 mA per-channel output near the supply rails. Rework is doable with hot air if you preheat the board to 100°C and use a fine-tip nozzle; the exposed pad gives you a visual alignment check when the part self-centers during reflow.

Temperature grade and deployment boundary

Fine for bench instruments, office equipment, audio gear, or indoor telecom — but do not spec it into a motor drive enclosure, engine bay, or outdoor cabinet without a temperature chamber test. The 450 µV input offset voltage is typical for a high-speed bipolar input stage; if you need sub-100 µV offset for precision DC, look at a chopper-stabilized amp instead.

Frequently asked questions

What is a functional equivalent or second-source for LT6231CDD#TRPBF?

The AD8028 has a higher slew rate (100 V/µs) and lower input offset voltage (200 µV), but comes in an MSOP-8 package rather than the DFN. Check the pinout and footprint before substituting — the packages are not drop-in compatible.
