LTC6268IS6#TRPBF 500 MHz FET input op amplifier
The LTC6268IS6#TRPBF is a 500 MHz ultra-low bias current FET-input operational amplifier manufactured by Analog Devices, belonging to the LTC6268/LTC6269 single/dual high-speed op-amp family. Supplied in a compact 6-lead TSOT-23 surface-mount package and shipped in tape-and-reel form, this RoHS-compliant, lead-free device is specified for the -40 °C to 85 °C industrial temperature range. As a single-channel amplifier, it operates from a 3.1 V to 5.25 V supply while consuming a modest 16.5 mA of quiescent current per amplifier. Combining a JFET/CMOS input stage with a rail-to-rail output stage, the LTC6268IS6#TRPBF is engineered for precision high-speed signal conditioning where femtoampere-level input bias current and wide bandwidth must coexist, making it a default building block for optically based and high-impedance sensing front-ends.
Owing to its ultra-low bias current, low noise, and 500 MHz bandwidth, the LTC6268IS6#TRPBF is extensively deployed as a high-speed transimpedance amplifier in photodiode receiver circuits, where it converts picoampere-scale photocurrents into clean voltage signals for optical communications, lidar, and precision light metering. The device's low distortion and rail-to-rail output make it an ideal ADC driver for SAR-based data-acquisition systems, high-speed DAQ boards, and mixed-signal measurement equipment that demand accurate settling without introducing harmonic error. Video and imaging systems leverage its bandwidth and slew rate for high-frequency signal conditioning and CCD pixel readout, while telecommunications and RF monitoring equipment adopt it for broadband, low-leakage signal buffering. In laboratory and test instruments, its femtoampere bias current supports ultra-high-impedance probe amplification, electrometer-class measurements, and charge-sensitive preamplification.
Alternative operational amplifier models
● LTC6268IS8#TRPBF: A single-channel LTC6268 in an 8-lead SOIC package offering the same 500 MHz FET-input amplifier specifications with the added advantage of two unconnected pins that can be configured as an input guard ring to eliminate board-level leakage currents in ultra-high-impedance designs.
● LTC6269IMS8E#PBF: The dual-channel version of the LTC6268 family in an 8-lead MSOP package with exposed pad, providing two matched 500 MHz ultra-low-bias amplifiers for multi-channel transimpedance arrays, stereo optical receivers, and parallel sensor-conditioning chains.
● LTC6268-10IS6#TRPBF: A decompensated gain-of-10-stable variant of the LTC6268 architecture in the same 6-lead TSOT-23 footprint, pushing the gain-bandwidth product to 4 GHz with a 1,500 V/µs slew rate for applications that can trade unity-gain stability for extreme speed.
