Key Features
- Ultra-low input bias current of 0.02 nA at 25°C, ideal for high-impedance sensor interfaces
- High common-mode rejection ratio minimum 77 dB (typical 95 dB) for excellent noise immunity
- JFET input stage with voltage-feedback architecture enabling wide dynamic range amplification
Applications
The LT1793CS8#PBF is well suited for precision analog signal conditioning where high-impedance sources such as photodiodes or piezoelectric sensors require amplification with minimal loading. Its low-noise JFET input makes it an excellent choice for instrumentation front-ends, medical signal acquisition, and precision data acquisition systems. The voltage-feedback topology also supports wide-bandwidth audio and test-equipment applications.

Frequently Asked Questions
What is the input bias current specification of LT1793CS8#PBF at room temperature?
At 25°C, the LT1793CS8#PBF has a maximum input bias current of 0.00002 µA (20 pA), making it extremely suitable for high-impedance signal sources such as photodiodes, pH electrodes, or piezoelectric sensors where loading must be minimized.
Which sensor interface designs benefit most from the LT1793CS8#PBF JFET input architecture?
Designs with high-impedance transducers benefit most. The JFET input provides less than 0.0005 µA bias current over temperature, and the 77 dB minimum CMRR suppresses common-mode interference in environments with 50/60 Hz noise, making it ideal for biomedical, industrial, and environmental monitoring front-ends.
How does LT1793CS8#PBF compare in package footprint to a DIP-8 op-amp alternative?
The LT1793CS8#PBF uses an SO-8 (SOIC-8) surface-mount package, which occupies roughly 5 mm × 4 mm board area — significantly smaller than a DIP-8 through-hole package at about 10 mm × 6.5 mm — enabling more compact PCB layouts in 8-pin single op-amp applications.
