Dual-channel speed and output drive
The LTC6247CDC#TRMPBF is a dual general-purpose op-amp with a 180 MHz gain-bandwidth product and a 90 V/µs slew rate, giving it the speed to handle fast signal edges in ADC driver or video buffer stages. The -3 dB bandwidth extends to 120 MHz, so the small-signal response stays flat well into the VHF range. Each of the two channels delivers 100 mA output current from a rail-to-rail output stage, meaning the output can swing within millivolts of either supply rail while sourcing or sinking enough current to drive a 50-ohm back-terminated line or a moderate capacitive load. Supply current is 1.25 mA per channel, keeping the total quiescent draw under 2.5 mA for the dual package.
Supply range and input offset
The part operates from a single supply span of 2.5 V to 5.25 V, so it runs directly from a 3.3 V or 5 V rail without a negative supply. Input offset voltage is 100 µV typical, and input bias current is 400 nA — both figures are low enough for precision DC-coupled stages in signal conditioning chains.
Package and footprint for layout
Housed in an 8-lead WFDFN with exposed pad (2 mm × 2 mm body), the LTC6247CDC#TRMPBF requires a thermal pad on the PCB for heat sinking. The exposed paddle is electrically connected to the die substrate — typically tied to the negative supply or left floating per the datasheet recommendation. The 0.50 mm pitch DFN footprint demands a solder-paste stencil aperture that matches the pad geometry; a 4-layer board with thermal vias under the pad improves thermal dissipation when the part is driving continuous 100 mA loads.
Temperature grade and deployment context
Rated for the commercial temperature range of 0°C to 70°C, this op-amp is suited for indoor bench equipment, lab instrumentation, and telecom line cards that operate in climate-controlled environments. It is not specified for automotive or extended industrial temperature — for -40°C to +125°C applications, the AD8028ARMZ-REEL7 or AD8030ARJZ-REEL7 are alternative dual rail-to-rail parts with wider temperature grades.
Lifecycle and compliance
The LTC6247CDC#TRMPBF carries an active lifecycle status and is ROHS3 compliant. The part is supplied in Tape & Reel (TR) or Cut Tape (CT) packaging, which is the standard format for automated pick-and-place assembly.
