Applications
The LTC6268HS8-10#TRPBF is engineered for transimpedance amplifier (TIA) designs in photodiode receivers, mass spectrometers, and optical communication front-ends where femtoampere-level input bias current is essential to avoid measurement errors at high source impedances. Precision instrumentation and chemical sensor interfaces deploy it to convert picoampere ion currents to measurable voltages without introducing offset from bias current across megaohm feedback resistors. Automotive LiDAR receiver designs leverage its 4 GHz GBW and automotive-grade rating to achieve sub-nanosecond pulse detection accuracy in temperatures ranging from -40°C to +125°C.

Frequently Asked Questions
What makes LTC6268HS8-10#TRPBF uniquely suited for photodiode transimpedance amplifier (TIA) designs?
LTC6268HS8-10#TRPBF achieves an input bias current of just 4 fA (femtoamperes) and a maximum of 2e-11 µA at 25°C, which is 1000x lower than typical JFET op-amps. In a TIA with a 10 MΩ feedback resistor, this bias current produces less than 0.04 µV of offset error, enabling accurate measurement of picoampere photodiode currents in optical sensing, fluorescence detection, and particle counting applications.
What gain-bandwidth product does LTC6268HS8-10#TRPBF provide and how does this affect its use in wideband sensor circuits?
LTC6268HS8-10#TRPBF provides a 4 GHz gain-bandwidth product at a fixed gain of 10, which means the -3 dB bandwidth reaches 400 MHz at 10x gain — far exceeding standard precision op-amps limited to 10 to 50 MHz. For wideband optical receivers and pulse-current sensing in LiDAR or time-of-flight systems, this bandwidth allows accurate amplification of nanosecond-duration current pulses without significant frequency rolloff at 100 MHz signal rates.
How does the automotive grade of LTC6268HS8-10#TRPBF differ from standard commercial grade versions in terms of operating temperature?
The H-grade (automotive) LTC6268HS8-10#TRPBF is specified and tested over a -40°C to +125°C junction temperature range, compared to the commercial I-grade tested to +85°C. Common-mode rejection ratio is guaranteed at minimum 50 dB across the full automotive range, ensuring the op-amp maintains precision performance in under-hood engine control modules, EV battery monitoring circuits, and automotive LiDAR receiver boards exposed to extreme thermal cycling.
For a precision chemical ion sensor reading currents below 10 pA, why is LTC6268HS8-10#TRPBF preferable to a standard op-amp with nanoampere bias current?
A standard op-amp with 1 nA input bias current would inject 1000x more leakage current than the ion signal itself into a 10 GΩ sensor electrode, creating a 10 V error — completely swamping the measurement. LTC6268HS8-10#TRPBF's 4 fA bias current introduces only 40 µV of error across the same 10 GΩ source impedance, allowing the TIA stage to faithfully convert sub-picoampere electrochemical or mass spectrometry ion currents into measurable millivolt-level output signals.
