What are the key features of LTC6269HMS8E-10#TRPBF?
- Ultra-low 2e-11 µA (20 fA) maximum input bias current at 25°C enables accurate current sensing from high-impedance photodiode and electrometer sources
- 4 GHz gain-bandwidth product supports wideband transimpedance amplifier designs operating across the MHz signal range
- 77 dB typical CMRR with 50 dB minimum ensures strong common-mode noise rejection in differential signal paths
- Voltage-feedback architecture with frequency compensation provides stable closed-loop operation at gains from 10 V/V and above
What is LTC6269HMS8E-10#TRPBF used for?
The LTC6269HMS8E-10#TRPBF is optimized for photodiode transimpedance amplifiers in optical receivers, lidar front-ends, and spectroscopy instruments where sub-picoampere input currents must be accurately converted to voltage. Its femtoampere bias current makes it equally suited to electrometer circuits, ion chamber readouts, and pH electrode buffers that present very high source impedances exceeding 1 GΩ. The compact MSOP-8 package supports high-density analog front-end PCBs in medical diagnostics and scientific instrumentation.

Frequently Asked Questions
How low is the input bias current of LTC6269HMS8E-10#TRPBF and why does it matter for photodiode circuits?
The maximum input bias current at 25°C is 2e-11 µA (20 fA), and the typical value is just 4 fA. In a photodiode transimpedance amplifier with a 10 GΩ feedback resistor, even a 1 pA bias error would produce a 10 mV output offset, so femtoampere-level bias is critical for accurate low-light measurements.
What gain-bandwidth product does LTC6269HMS8E-10#TRPBF support, and at what closed-loop gain is it typically used?
The LTC6269HMS8E-10 provides a 4 GHz gain-bandwidth product. At a closed-loop gain of 10 V/V, the usable bandwidth extends to approximately 400 MHz, making it suitable for wideband transimpedance stages in optical receivers and time-of-flight lidar systems operating well above 100 MHz.
Which package does LTC6269HMS8E-10#TRPBF come in and what is the lead-finish status?
The device is supplied in an MSOP-8 (SOT-23-8 style) small-outline package with a non-RoHS lead-finish (Pbfree Code: No), as indicated by the #TRPBF tape-and-reel suffix. The 8-pin package occupies less than 15 mm² of board area, suitable for compact analog front-end layouts with guard rings around the high-impedance input pins.
When should LTC6269HMS8E-10#TRPBF be chosen over a standard low-noise op-amp like LT1028?
Choose LTC6269HMS8E-10#TRPBF when source impedance exceeds 100 MΩ and bias current error dominates total noise — its 20 fA maximum bias is orders of magnitude lower than LT1028's 30 nA, eliminating picoampere-scale offset errors. LT1028 is preferable only when voltage noise below 1 nV/√Hz at 1 kHz is the primary constraint and source impedance is below 10 kΩ.
