What this dual op-amp delivers for high-speed signal chains
The LT6231IDD#PBF is a dual-channel general-purpose op-amp from the LT® series, offering a 215 MHz gain-bandwidth product and 70 V/µs slew rate. That combination means it can handle fast pulse edges and wideband analog signals without slew-induced distortion — a common pain point in ADC driver stages or video buffers where a slower part would round off the waveform. Each channel delivers rail-to-rail output swing, which maximizes dynamic range when running from a single 3 V to 12.6 V supply. The 3.3 mA per-channel supply current keeps the thermal budget manageable in a dual-channel layout.
Package and mounting
At 215 MHz GBW, the LT6231IDD#PBF sits above general-purpose op-amps like the AD8646 (24 MHz, 11 V/µs), but below the AD8028 (190 MHz, 100 V/µs). The 70 V/µs slew rate is enough to reproduce a 10 MHz, 2 Vpp sine wave with less than 1% distortion — a practical benchmark for signal-chain design. Output current is rated at 30 mA per channel, which can drive a 50-ohm load to about 1.5 Vpp — useful for RF or video line driving where a dedicated buffer might otherwise be needed.
Package and thermal considerations for the 8-DFN footprint
The 8-WFDFN exposed pad package measures 3x3 mm and requires a thermal via array under the pad to pull heat into the PCB ground plane. Without that, the junction temperature rise at 30 mA output on both channels will exceed the datasheet's derating curve.
