Product details

Dual op-amp in a TSOT-23-8 footprint

Its 180 MHz gain-bandwidth product and 90 V/µs slew rate suit it for high-speed signal conditioning, ADC drivers, and video buffering where board area is tight.

Supply rails and quiescent draw

Each amplifier draws 1.25 mA supply current, so the dual channel total is 2.5 mA quiescent — a reasonable budget for a 120 MHz part. The 400 nA input bias current is low enough for most high-impedance sources, though precision DC applications below 1 kΩ source resistance may want a JFET-input alternative.

Slew rate and bandwidth — what they drive

The 90 V/µs slew rate and 120 MHz -3 dB bandwidth mean this part can handle fast pulse edges and wideband signals. For an ADC driver driving a 10-bit, 20 MSPS converter, the settling time to 0.1% will be well under 100 ns. The 100 mA output current per channel gives enough drive to swing into 50 Ω loads or to charge a 10 pF sampling capacitor in a few nanoseconds. Keep the feedback resistor values below 1 kΩ to avoid pole interactions with the 1.5 pF input capacitance.

Lifecycle and supply posture

ROHS3 compliant. Availability is confirmed through independent distribution; pricing and lead time are quoted per order against an RFQ.

Temperature grade — industrial, not automotive

It is not qualified to AEC-Q100, so it is not a direct fit for under-hood or chassis-mounted automotive modules without additional qualification data.

Frequently asked questions

Does LTC6247ITS8 have a rail-to-rail output?

Yes, the output stage is rail-to-rail, allowing the output to swing within a few millivolts of the positive and negative supply rails. The input common-mode range is not rail-to-rail — it extends from the negative rail to about 1.1 V below the positive rail at 3.3 V supply.

When sourcing LTC6247ITS8#TRMPBF, what is the closest functional second-source?

The AD8030ARJZ-REEL7 is a close parametric peer: dual rail-to-rail output op-amp with 125 MHz bandwidth and 63 V/µs slew rate, in a similar SOT-23-8 footprint. The LTC6247 offers a higher slew rate (90 V/µs vs 63 V/µs) and slightly lower bandwidth (120 MHz vs 125 MHz). The AD8030 extends the temperature range to 125°C, which may matter for some environments. Pin compatibility should be verified against the respective datasheets.
