Product details

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

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.

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.
