Frequently Asked Questions
How low is the input bias current of the LTC6268IS8-10#TRPBF and why does it matter for photodetector circuits?
The LTC6268IS8-10#TRPBF has a maximum input bias current of 2×10⁻¹¹ µA (20 fA) at 25°C and an average max of 9×10⁻⁷ µA. In trans-impedance amplifier designs with feedback resistors of 1 MΩ or more, this femtoampere-level bias current introduces negligible DC offset voltage, making it essential for accurate photodetector and optical power measurement circuits.
What bandwidth does the LTC6268IS8-10#TRPBF offer and which high-speed sensing applications benefit most?
The LTC6268IS8-10#TRPBF provides a 4 GHz gain-bandwidth product, enabling wideband trans-impedance amplifier designs for lidar receivers, optical communication front-ends, and high-speed current measurement systems. This 4 GHz bandwidth, combined with the 2 fA input bias current and 50 dB minimum CMRR, allows it to amplify fast optical pulses with sub-nanosecond rise times without introducing offset from bias leakage.
When is the LTC6268IS8-10#TRPBF preferred over a standard JFET op-amp for impedance spectroscopy?
For impedance spectroscopy and electrochemical sensing applications using source impedances above 1 MΩ, the LTC6268IS8-10#TRPBF is preferred because its 2 fA input bias current causes less than 2 µV of offset across a 1 GΩ source impedance, far superior to typical JFET op-amps with 10 pA to 100 pA bias currents. Its 4 GHz bandwidth additionally supports fast impedance measurements at frequencies up to hundreds of megahertz.
